Nature:
-Appearance: White crystalline solid
-Melting point: 174-175°C
-Boiling point: 359°C
-Solubility: Soluble in alcohol and ether solvents, insoluble in water
-Chemical properties: neutral substance in water, can be oxidized, reduced and addition reaction
Use:
- 2,4-dihydroxybenzonitrile is an important organic intermediate for the synthesis of drugs, dyes and heterocyclic compounds.
-It can be used to synthesize organic compounds containing benzonitrile groups and has a wide range of applications.
Preparation Method:
- 2,4-dihydroxybenzonitrile can be prepared by the reaction of 4-nitrosalicylic acid and sodium cyanide. First, 4-nitrosalicylic acid is reacted with sodium cyanide under alkaline conditions to give sodium 4-cyanosalicylate, which is then reduced (e. g. with sodium nitrite) to give 2,4-dihydroxybenzonitrile.
Safety Information:
-2,4-dihydroxybenzontril produces toxic gases under flammable conditions, which can irritate the eyes, skin and respiratory tract. Use should pay attention to protective measures, avoid contact with skin, eyes and respiratory tract.
-In storage and handling, should be stored in a dry, well-ventilated place, away from fire and flammable materials.
-When using, storing and handling this compound, carefully read and follow the instructions and safety instructions in the relevant Safety Data Sheet (SDS).
