2,3-diaminophenol - Introduction
2,3-diaminophenol(2,3-diaminophenol) is an organic compound with a chemical formula of C6H8N2O, two amino groups and one hydroxyl group, and the molecular structure is as follows:
H
|
H-NH2
|
H-C6H4-OH
|
H-NH2
2,3-diaminophenol is a white crystalline solid, soluble in water and ethanol at room temperature. It has some important properties and uses.
Nature:
- 2,3-diaminophenol is a weak acid alkaline substance that reacts with strong acids to form salts.
-It presents a dark blue color reaction in the solution, so it can be used as a color reagent in chemical analysis.
-It has the properties of a dye and can be used as a dye precursor.
Use:
- 2,3-diaminophenol can be used in the production of hair coloring agents, which can react with oxidants to form oxidative dyeing substances.
-It can also be used in the manufacturing process of dyes and pigments as a synthetic intermediate for dyes.
-In addition, 2,3-diaminophenol is also used to manufacture certain pharmaceutical compounds and photosensitive materials.
Preparation Method:
2,3-diaminophenol can be prepared by the reduction reaction of p-nitroaniline. First, 2,3-dinitroaniline is reacted with a reducing agent (such as sodium sulfinate or sodium nitrite, etc.), and then the resulting product is subjected to acid treatment to obtain 2,3-diaminophenol.
Safety Information:
Under proper use and storage, 2,3-diaminophenol is a relatively safe compound. However, it still has a certain toxicity, so appropriate protective measures should be taken when handling. Contact with skin, eyes and respiratory tract should be avoided, and protective glasses, gloves and masks should be worn when using. If you come into contact with 2,3-diaminophenol, rinse immediately with plenty of water and seek medical help.
