4-Hydroxyazobenzene-4-sulfonic acid - Introduction
acid is an organic compound with the chemical formula C12H10N2O4S. It is a dark red crystalline powder that is soluble in water and ethanol. The following is a detailed description of the properties, uses, preparation and safety information of this compound:
Nature:
-Appearance: dark red crystal powder.
-Solubility: Soluble in water and ethanol.
-Melting point: About 250-260°C.
-Molecular weight: 282.3g/mol.
Use:
-must acid can be used as a precursor for dyes, photosensitive materials, and molecular switches.
-It can also be used as an indicator in a chemical laboratory.
Method:
-The preparation method of acid can be achieved by para-substitution reaction. First, the aniline group is introduced on the benzene sulfonic acid, and then it is oxidized to the imide group, and the azo compound is produced by diazotization reaction. Finally, the azo compound is reduced to acryl.
Safety Information:
-the acid may be irritating to the eyes, skin and respiratory system and should be avoided.
-Wear appropriate personal protective equipment such as chemical goggles, protective gloves and protective masks during operation.
-Avoid contact with oxidants during storage, avoid accumulation of static electricity, and keep away from open flames and high temperatures.
-In case of accidental ingestion, accidental breathing or skin contact, seek medical attention immediately and provide the outer packaging or chemical label to the doctor.
