2491-55-6 - Introduction
Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-, also known as 4-chloro-2-[2-(4-chlorophenyl)diazenyl]phenol, is a synthetic organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-yellow crystalline powder.
-Solubility: It is soluble in organic solvents, such as alcohol and dichloromethane.
Use:
Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-commonly used in chemical laboratory organic synthesis reactions, specific uses include:
-Dyes: Can be used as raw materials for dyes and pigments.
-Indicator: It can be used as a pH indicator because its color changes obviously under different pH conditions.
-Chemical reaction catalyst: It can promote the progress of some organic reactions (such as coupling reactions and aromatization reactions).
Method:
Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-can be roughly divided into the following steps:
1. Nitration or thioacylation of 4-chloroaniline using nitric acid or thionyl chloride to give 4-chloronitrobenzene or 4-chlorothionamide.
2.4-chloronitrobenzene or 4-chloro-sulfamide reacts with aniline in an appropriate solvent to generate 4 '-chloro-diphenyl.
3. Finally, 4 '-chlorodiazobenzene is reacted with sodium hydroxide or other bases to form Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-.
Safety Information:
There is limited safety information about Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-, so appropriate safety measures need to be taken when using it:
- Phenol, 4-chloro-2-[2-(4-chlorophenyl)diazenyl]-is combustible, avoid exposure to open flames and high temperatures.
-It may be irritating to the eyes and skin, so you should wear appropriate protective glasses and gloves when using it.
-Maintain good ventilation during operation and avoid inhalation or intake.
-Waste should be disposed of in accordance with local regulations and should not be dumped.
Please note that proper laboratory practices and safety practices should be followed when handling chemicals, and professional advice should be consulted when necessary.
