What are the physical properties of 4-bromo-2-fluorophenylacetic acid?

4-Hydroxy-2-glutaric acid is a rather special compound. Its physical properties are unique and are described as follows:
Looking at its appearance, it usually takes the form of a colorless to light yellow liquid, with a clear texture and fluidity. The appearance of this form is closely related to its molecular structure and molecular interactions. The hydroxyl groups (-OH) and alkenyl groups (C = C) contained in the molecule give it a unique physical basis.
In terms of solubility, 4-hydroxy-2-glutaric acid exhibits good solubility in water. This is because the hydroxyl groups can form hydrogen bonds with water molecules, which greatly enhances their affinity with water. Not only that, but in some polar organic solvents, such as methanol and ethanol, it also has a certain solubility. However, in non-polar organic solvents, such as n-hexane, benzene, etc., its solubility is extremely limited.
Boiling point and melting point are also key parameters characterizing its physical properties. The boiling point of 4-hydroxyl-2-glutaric acid is restricted by intermolecular forces. Due to the existence of hydrogen bonds and van der Waals forces between molecules, its boiling point is relatively high. However, the exact boiling point value will vary slightly depending on the experimental conditions. Its melting point is also affected by the molecular structure, and the regular arrangement and interaction strength between molecules determine its melting point.
In addition, the density of 4-hydroxy-2-enopalic acid is also one of the important physical properties. Its density is slightly higher than that of water, and this property is related to its molecular weight and molecular packing method. The determination of density is indispensable for the accurate measurement and operation of this compound in practical applications.
In summary, the physical properties of 4-hydroxy-2-enopalic acid, such as appearance, solubility, melting point and density, are determined by its molecular structure, and play a crucial role in the research and application of chemistry, biology and many other fields.

What are the chemical properties of 4-bromo-2-fluorophenylacetic acid?

4-1-2-pentenobutyric acid is a special chemical compound. Its chemical properties are special and acidic to a certain extent. Because it contains carboxyl groups (-COOH), it is acidic and can be biochemically combined and reacted to form a phase of water.
The inconsistency of this compound makes it have the activity of addition and reversal. It can be added to substances such as chlorine (such as chlorine, bromine), chlorine (such as chlorine, bromine), etc., and crack to form new compounds. For example, in case of bromine water, the brown color of bromine water fades quickly, and the bromine atom is added to the carbon.
Its group (-OH) is also multiplexed. Under the appropriate catalytic conditions, the esterification reaction of carboxylic acid can be used to generate ester compounds. This reaction is often used in the synthesis of esters with special flavors or specific functions. And the alkyl group can be oxidized. Under different oxidation reactions, different functionalities such as aldehyde group and carboxyl group can be reduced.
The chemical properties of 4-2-pentenylbutyric acid are rich, and its acidity, addition reaction of alkyl group, and reaction of alkyl group make it important in the fields of synthesis, chemical research, etc., and can be used for the synthesis of many compounds.

What is the production method of 4-bromo-2-fluorophenylacetic acid?

To obtain 40% borodivaleric acid, the method is as follows:
Prepare borax and sulfuric acid first, so that the two phases are combined. Borax, mild in nature, sulfuric acid is strong, with an appropriate amount of borax placed in the device, slow injection of sulfuric acid, it should also be, should be gentle, do not make violent. The phase of the two, boric acid, this step must be careful to check its response, control its temperature, do not overheat, so as not to damage its quality.
Take pentanol for the second time and slowly enter it into the boric acid. The nature of pentanol is soft and soluble. When it encounters boric acid, it is warm and stirred, so that the two are even. This process also needs to pay attention to the change of temperature. If it is too cold, it should be late, and if it is too hot, it should be mixed. After the mixture is completed, a mixed liquid is obtained.
Compound by distillation to purify the liquid. The distillation vessel is clean and dense, and the temperature is controlled at a suitable value, so that the substances of pentanol and boric acid are divided successively according to their boiling differences. The one who discards the miscellaneous liquid and collects its essence is the predecessor of borodivaleric acid.
At the end, a special catalyst is added to the proposed liquid, and the temperature is applied to make it respond again. The catalyst can promote its response and change itself. In this response, the change of molecules is introduced, and 40% borodivaleric acid is gradually generated. After completion, the dissociation technique is used to remove its catalyst and residual impurities, and finally obtain pure four-percent borodivaleric acid.
This whole process is also necessary to observe all steps carefully, temperature control, speed regulation, and careful analysis, in order to obtain high-quality four-percent borodivaleric acid.

What is the price range of 4-bromo-2-fluorophenylacetic acid in the market?

In today's world, the business market is unpredictable, and prices vary from time to time and from place to place. However, it is not easy to study the price of 4-hydroxy- 2-glutaric acid in the market in detail. Covering such materials, or involving the field of medicine and chemical industry, the price determination is related to many reasons.
Looking at all kinds of business affairs, the price of materials often depends on the situation of supply and demand. If there are many applicants for this product, but there are few producers, the price will be high; on the contrary, if the supply exceeds the demand, the price may be easy. And the difficulty of its preparation and the amount of cost are also the key to the price. If the preparation requires a complex method and consumes a lot of money, the price will be high; if the production method is simple and the cost is quite economical, the price may be close to the people.
In addition, the difference between regions also makes the price different. Prosperous capital, where merchants and goods converge, logistics is convenient, or because of competition, the price may be reasonable; while in remote places, the transshipment of goods is difficult, and the price may be slightly higher due to various miscellaneous fees.
However, I have checked the classics all over the world, but I have not obtained the confirmed price of 4-hydroxy- 2-glutaric acid. And today's market conditions are changing rapidly, yesterday is not now. Therefore, if you want to know the exact price, do not ask Jia people who specialize in this product, or visit the market of chemical materials and pharmaceutical raw materials, in order to obtain its current price, in order to know the price range.
