By reacting with different reagents, a variety of color systems can be constructed, such as azo dyes. Such dyes are widely used in fabric printing and dyeing, which can give fabrics rich and long-lasting color, and are not easy to fade under sun exposure, washing and other conditions, so they are crucial in the textile industry.
In the field of medicine, 3-hydroxyethylaminonaphthalene has potential medicinal value. Due to its special chemical structure, it can be used as a lead compound. After structural modification and optimization, it is expected to develop drugs with specific pharmacological activities. For example, in some studies, it has been found to have a certain effect on the relevant targets of specific diseases, or it can be used to develop antibacterial, anti-inflammatory and other drugs, providing assistance for human health.
In the field of organic synthesis, it is an extremely important basic raw material. With its structural activity check point, it can participate in the synthesis of many complex organic compounds. Chemists can use it for nucleophilic substitution, condensation and other reactions to construct complex organic frameworks, laying the foundation for the synthesis of organic materials with special functions and structures, and playing an indispensable role in the development of materials science.

3-Hydroxyacetylbenzene, also known as acetylphenol, is an organic compound. Its physical properties are quite unique, as detailed below:
- ** Appearance and Properties **: Under normal conditions, 3-hydroxyacetylbenzene is in the state of white to light yellow crystalline powder, which is fine in appearance and uniform in texture. This form is easy to store and use, and in many chemical reactions, powdered substances are easier to disperse, which can promote the reaction to proceed more fully and efficiently.
- ** Melting Boiling Point **: The melting point is between 108 ° C and 112 ° C, and the boiling point is about 313 ° C. This melting boiling point characteristic determines its physical state change at different temperatures. Below the melting point, it remains a solid state stably; when the temperature rises above the melting point and below the boiling point, it will transform into a liquid state; and once the temperature exceeds the boiling point, it will vaporize into a gaseous state. This temperature-dependent state transition is of crucial significance in the separation, purification and certain specific chemical reactions of substances, and can provide a key temperature basis for related operations.
- ** Solubility **: Soluble in organic solvents such as ethanol, ether, and chloroform, but insoluble in water. This solubility characteristic is closely related to its molecular structure. The molecule contains not only lipophilic benzene rings and acetyl groups, but also hydrophilic hydroxyl groups. However, in general, the lipophilic part is dominant, causing it to exhibit good solubility in organic solvents, but very little solubility in water. This characteristic is widely used in organic synthesis, drug development and other fields. For example, when extracting or separating mixtures containing 3-hydroxyacetylbenzene, a suitable solvent can be selected according to its solubility to achieve efficient separation.
- ** Odor **: It has a weak and special odor. Although this odor is not strong and pungent, it still has certain uniqueness and can be used as one of the auxiliary characteristics to identify the substance. In actual operation and use, by perceiving this special odor through the sense of smell, it is possible to initially determine whether there is 3-hydroxyacetylbenzene, but the odor discrimination needs to be cautious to avoid adverse effects on the human body due to excessive inhalation.

The chemical properties of 3-hydroxyethyl aminosilane are quite stable. In its molecular structure, silicon atoms are connected to oxygen atoms, carbon atoms, etc., to form a stable structure. In this compound, the silicon-oxygen bond energy is quite high, giving it a certain chemical stability and resisting the erosion of many common chemical reagents.
In terms of its stability, under normal environmental conditions, under normal temperature and pressure, it is not easy to decompose and polymerize on its own. In the conventional acid-base environment, it also shows a certain resistance. When encountering weak acids, its structure is difficult to be easily destroyed because its silica skeleton has good tolerance; when encountering weak bases, it can also maintain its own structure integrity and its chemical properties remain stable.
However, although its properties are stable, under certain extreme conditions, it will also change. If the temperature rises sharply, beyond its tolerance range, the chemical bond energy inside the molecule may be weakened, which in turn triggers structural changes and chemical reactions. Strong oxidizing agents may also break its stable structure, resulting in changes in chemical properties.
But overall, in common use scenarios and common environments, 3-hydroxyethylamino silicon is chemically stable and can meet the needs of many practical applications. It is widely used in many fields such as textiles, leather, construction, etc. Its stability characteristics endow materials with unique properties and excellent quality.

There are various ways to prepare 3-hydroxyethylaminonaphthalene. One method is to use naphthalene as a group to react with ethylene oxide under suitable conditions. This reaction requires the selection of appropriate catalysts, such as certain metal salts or organic bases. In a controlled temperature and pressure environment, the activity check point of naphthalene can undergo nucleophilic substitution with ethylene oxide, and then the hydroxyethylamino group is introduced to generate 3-hydroxyethylaminonaphthalene.
Another method is to nitrate the naphthalene first to obtain the nitronaphthalene derivative, then reduce the nitro group to an amino group, and then react the amino-containing naphthalene derivative with the hydroxyethylation reagent. For example, halogenated ethanol is selected as the hydroxyethylation reagent. Under basic conditions, the amino group is substituted with the halogen atom of halogenated ethanol to form 3-hydroxyethylamino naphthalene. In this process, the reaction conditions for reducing the nitro group and controlling the hydroxyethylation step are quite critical. The reaction temperature, reagent ratio and reaction time need to be carefully adjusted to ensure the purity and yield of the product.
Another way is to use the naphthalene derivative containing a specific substituent as the starting material and gradually construct the structure of 3-hydroxyethylamino naphthalene through a multi-step organic synthesis reaction. Although this method is complicated, the synthesis route can be flexibly adjusted according to the characteristics of the desired product. Synthesis often involves a variety of organic reactions such as acylation, alkylation, hydrolysis, etc. Each step of the reaction needs to be carefully controlled to achieve the desired preparation goals.
All preparation methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively weigh factors such as raw material availability, cost considerations, and product purity requirements to choose the best method.

3-Hydroxyethylaminopropionitrile is in the market, and its price is uncertain, often depending on quality, quantity and market conditions.
Looking at various cities, the price of such a product may be tens of gold per kilogram, or over 100 gold. If its quality is high and the quantity is huge, the supplier may offer a preferential price, and the price may decrease; if the quality is average and the quantity is small, the price may be slightly higher.
In addition, the supply and demand of the city also affect its price. If there are many needs and few suppliers, the price will rise; if the supply exceeds the demand, the price will drop. Furthermore, the cost of production, including raw materials, labor costs, transportation costs, etc., are all affected by the price. If the raw materials are expensive, the labor cost is high, and the transportation cost is huge, the price of this product will increase; otherwise, the price may decrease.
Therefore, if you want to know the exact price of 3-hydroxyethylaminopropionitrile, you should consult the supplier or observe the real-time market conditions before you can get an accurate number. The market conditions are ever-changing, and the price is also impermanent. Those who need it should be carefully observed and considered.
