(2,3,5,6-tetrafluoro-1,4-phenyldimethanol), also known as perfluoro-1,4-phenylenedimethanol, this substance has unique physical properties. Its appearance is white to off-white crystalline powder, which is stable in conventional environments and easy to store and transport.
In terms of melting point, it is about 145-149 ° C. This characteristic makes it a phase transition at a specific temperature range. In the field of material synthesis and other fields, the melting point can be used to control the reaction process and product purity. For example, when preparing composites containing this component, choose the appropriate processing temperature according to the melting point to ensure that it is uniformly mixed with other materials.
In terms of solubility, slightly soluble in water, but easily soluble in some organic solvents, such as dichloromethane, chloroform, etc. This solubility property is of great significance in chemical separation and purification. It can be used to separate or purify the substance from the mixture by taking advantage of the difference in solubility in different solvents. For example, in the post-treatment of organic synthesis reaction products, the solubility is used to separate them from the reaction system to improve the purity of the product.
In terms of density, the relative density (water = 1) is about 1.6 - 1.7. This value indicates that it is heavier than water. In systems involving liquid-liquid separation or water-related systems, its distribution in the system can be predicted based on this property. For example, in a heterogeneous system where water and the substance are mixed, it will be in the lower layer.
In addition, the substance also has certain stability and low volatility. Under normal storage and use conditions, it is not easy to evaporate and lose, and it can maintain its chemical composition and properties unchanged for a long time, providing protection for its stable performance in various application scenarios. For example, in chemical raw materials or finished products stored for a long time, its stable properties can ensure that product quality is not affected by time.

(2,3,5,6-tetrafluoro-1,4-phenyldimethanol), also known as perfluoro-1,4-phenylenedimethanol, this substance has unique chemical properties. Its appearance is mostly white to off-white crystalline powder, and its properties are stable, which is due to the structure of benzene ring and fluorine atoms.
From the perspective of physical properties, the melting point is in a specific range, which is determined by intermolecular forces and structural order. In organic synthesis, this melting point characteristic can help to separate and purify. It is slightly soluble in water, but easily soluble in common organic solvents such as ethanol, acetone, etc. This solubility is conducive to being used as reactants or intermediates in different reaction systems.
In terms of chemical properties, due to the influence of benzene ring and fluorine atoms, it has certain aromaticity and chemical stability. The strong electronegativity of fluorine atoms causes the distribution of its electron cloud to change, which reduces the density of electron clouds on the benzene ring, and the activity of electrophilic substitution is weaker than that of benzene. However, under certain conditions, hydroxyl groups can participate in a series of reactions, such as esterification reactions, and can form corresponding esters with organic acids or inorganic acid anhydrides under the action of catalysts, which can be used to prepare fluorine-containing functional materials or pharmaceutical intermediates. It can also be oxidized. Under the action of suitable oxidizing agents, hydroxyl groups may be converted into aldehyde groups, carboxyl groups, etc., providing various routes for organic synthesis.
In addition, the fluorine-containing properties of this substance give it special properties, such as certain corrosion resistance, low surface energy, etc., which are particularly advantageous in the field of materials science or in special environmental applications.

The method for preparing (perfluoro-1,4-phenylene) dimethanol (2,3,5,6-tetrafluoro-1,4-phenyldimethanol) covers several routes.
One of them can be started by fluorobenzaldehyde. Take an appropriate fluorobenzaldehyde, such as 2,3,5,6-tetrafluorobenzaldehyde, and treat it with a reducing agent. Commonly used reducing agents such as sodium borohydride (NaBH), in a suitable solvent, such as alcohol solvent, such as methanol or ethanol, react at low temperature to room temperature. Sodium borohydride can reduce aldehyde groups (-CHO) to hydroxymethyl groups (-CH 2O OH). During the reaction, stir well to make the reducing agent fully contact with the aldehyde. After the reaction is completed, the target product can be obtained after post-processing steps such as dilution with water, extraction, drying, distillation or recrystallization.
Second, fluorohalobenzene can also be used as raw material. First, fluorohalobenzene is reacted with magnesium to make Grignard reagent. For example, 2,3,5,6-tetrafluorobromobenzene and magnesium are reacted with anhydrous ether or tetrahydrofuran to make Grignard reagent. Then, the Grignard reagent is reacted with formaldehyde to introduce hydroxymethyl groups. After the reaction is completed, (perfluoro-1,4-phenylene) dimethanol can also be obtained through hydrolysis, separation and purification. During operation, attention should be paid to the anhydrous and oxygen-free reaction environment to ensure the activity of Grignard reagent.
Or, prepared by nucleophilic substitution of fluorobenzene. Select suitable fluorobenzene derivatives and react with nucleophilic reagents, such as hydroxymethyl-containing nucleophilic reagents, in the presence of suitable bases and solvents. After careful reaction control and subsequent purification, the purpose of preparation can also be achieved.

I think what you are asking is about the price range of (2,3,5,6-tetrafluoro-1,4-phenyldimethanol) in the market. However, the price of these materials often changes for many reasons, and it is difficult to determine its fixed number.
If the common factors are studied, one is the source of the material. If the raw materials are easy to harvest and abundant, the price may be flat; if the raw materials are rare and expensive, the price must be high. The second is related to the craftsmanship. If the method of making is simple and efficient, the cost will drop and the price will also drop; if the craftsmanship is difficult, the cost will increase and the price will increase. Third, the supply and demand of the city are also heavy. Those who ask for a lot and those who supply a few will increase the price; if the supply exceeds the demand, the price will fall.
And different places and different merchants have different prices. In prosperous cities, there are many merchants, fierce competition, or those with good prices; in remote places, the circulation of goods is difficult, and the price may increase. In addition, the amount of purchase also affects the price. For bulk buyers, merchants often give discounts.
Then check the past transactions, the price of this (2,3,5,6-tetrafluoro-1,4-phenyldimethanol) is between tens and hundreds of yuan per gram. This is only an approximate number. The actual price can be determined only by consulting the merchants of chemical materials or observing it on a special trading platform.
