4-Bromo-3-fluorobenzyl the physical properties of alcohol

4-Bromo-3-fluorobenzyl alcohol, this is an organic compound. Its physical properties are quite characteristic. At room temperature, it is mostly colorless to light yellow liquid, but it may also be slightly different in color due to some impurities or environmental factors.

Looking at its smell, it has a special aromatic smell. However, it is not rich and strong, but more elegant, but its taste still has a certain degree of recognition.

When it comes to the melting point, the melting point is usually low, in the range of relatively low temperature. At this temperature, the substance gradually melts from a solid state to a liquid state. The boiling point is relatively moderate. Under specific pressure conditions, the substance changes from a liquid state to a gas state.

Its solubility also follows a regular pattern. In organic solvents, such as ethanol and ether, it exhibits good solubility and can be miscible with them. This property is due to the interaction between its molecular structure and the molecules of organic solvents. However, in water, the solubility is poor, because the polarity of the molecule and the polarity of the water molecule are not well matched, so it is difficult to dissolve in large quantities.

In terms of density, it is heavier than water. If it is placed in the same container as water, it will sink to the bottom, which is determined by the mass and spatial arrangement of its molecules.

In addition, the volatility of 4-bromo-3-fluorobenzyl alcohol is relatively weak, and the rate of molecular escape from the liquid surface is relatively slow under normal temperature and pressure, which contributes to its stability during storage and use. In summary, the physical properties of 4-bromo-3-fluorobenzyl alcohol are of great significance in organic synthesis, chemical analysis and other fields, laying the foundation for related research and applications.

4-Bromo-3-fluorobenzyl chemical synthesis of alcohol

The chemical synthesis of 4-bromo-3-fluorobenzyl alcohol is an important topic in the field of organic synthesis. To make this substance, it can be achieved through multiple paths.

One method can be started from 4-bromo-3-fluorobenzoic acid. First, 4-bromo-3-fluorobenzoic acid is added dropwise under suitable reaction conditions, such as in anhydrous ether or tetrahydrofuran in an inert solvent, low temperature and strictly anhydrous and anaerobic environment. This process needs to be carefully monitored because of its intense reaction. After this reduction reaction, the carboxyl group (-COOH) of benzoic acid can be converted into hydroxymethyl (-CH 2O OH), and 4-bromo-3-fluorobenzyl alcohol is obtained.

The second way, 4-bromo-3-fluorobrobenzyl can be used as the raw material. 4-bromo-3-fluorobrobenzyl is reacted with an appropriate amount of alkali metal hydroxide, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), in a water-organic solvent mixed system with the help of a phase transfer catalyst, such as tetrabutylammonium bromide (TBAB). This reaction requires controlling the temperature and the ratio of reactants. The phase transfer catalyst can promote the reaction to proceed efficiently between the two phases, and the bromine atom is replaced by a hydroxyl group to obtain 4-bromo-3-fluorobenzyl alcohol.

Or, 4-bromo-3-fluorobenzaldehyde is used as the starting material. Using sodium borohydride (NaBH) as the reducing agent, sodium borohydride is milder and easier to control than lithium aluminum hydride. In alcoholic solvents such as methanol or ethanol, the aldehyde group (-CHO) of 4-bromo-3-fluorobenzaldehyde can be reduced to hydroxymethyl (-CH 2O OH), and the target product 4-bromo-3-fluorobenzyl alcohol can be obtained.

The above synthesis methods have their own advantages and disadvantages. In actual operation, the choice needs to be weighed according to the availability of raw materials, the difficulty of reaction conditions, the purity and yield of the product, etc., in order to achieve the best synthesis effect.

4-Bromo-3-fluorobenzyl alcohol during storage and transportation

4-Bromo-3-fluorobenzyl alcohol is a kind of organic compound. When storing and transporting, all matters need careful attention.

First words storage, this compound should be placed in a cool, dry and well-ventilated place. Its properties may be affected by changes in temperature and humidity, and if it is placed in a warm and humid place, it may deteriorate. As "Tiangong Kaiwu" says, "Those who hide all things must choose a good place", which is also called. Storage should also be kept away from fire and heat sources, because the compound may be flammable, and it is prone to danger in case of open flames and hot topics. And it needs to be stored separately from oxidants, acids, etc., and cannot be mixed to prevent chemical reactions and accidents.

As for transportation, it should not be neglected. Before transportation, be sure to ensure that the packaging is complete and sealed. Packaging materials must be able to resist vibration, collision, and prevent leakage. "Tiangong Kaiwu" says that the goods transported are "firmly sealed to prevent damage", and the same is true. During transportation, you should follow the prescribed route and avoid densely populated areas and important areas. When driving, drivers should drive carefully to avoid sudden braking, sharp turns, etc., which will cause damage to the packaging and material leakage. Escort personnel should also pay attention to the condition of the goods at any time, and if there is any abnormality, they should dispose of it quickly.

In addition, whether it is storage or transportation, the relevant operators should be familiar with the characteristics of this compound and emergency treatment methods. In case of leakage and other accidents, the correct measures can be taken quickly to reduce the harm. In this way, the safety of 4-bromo-3-fluorobenzyl alcohol during storage and transportation can be guaranteed.

What is the market price of 4-Bromo-3-fluorobenzyl alcohol?

The market price of 4-bromo-3-fluorobenzyl alcohol is difficult to determine. Due to the changeable market conditions, its price often varies with changes in supply and demand, differences in origin, poor quality, and the amount purchased.

Looking at past market conditions, in places where chemical reagents are traded, if they are of ordinary purity and purchased in small quantities, the price per gram may range from tens of yuan to hundreds of yuan. However, if the demand is large, after negotiating with suppliers, the unit price may fluctuate.

If viewed from the source of production, the cost is controllable and the price is low when the raw materials are easily available and the process is simple. On the contrary, if the raw materials are scarce and the preparation is difficult, the price must be high.

Moreover, regional differences also affect their prices. In prosperous cities and convenient transportation, due to smooth logistics and fierce competition, prices may be stable; in remote places, due to increased transportation costs, prices may rise.

And the market conditions are changing rapidly. The advent of new production processes and the addition of new suppliers can make the price of 4-bromo-3-fluorobenzyl alcohol fluctuate. Therefore, if you want to know the exact market price, you must consult the chemical raw material supplier, chemical reagent sales platform, or go to the chemical market survey in real time to get accurate prices.
