74626-47-4 - Introduction
1H-indazole-5-carbonitril (1H-indazole-5-carbonitril) is a chemical substance that has the following properties:
1. Appearance: colorless or light yellow crystalline powder.
2. Solubility: Soluble in most organic solvents, such as ethanol, dimethyl sulfoxide and chloroform.
3. melting point: about 130-135 ℃.
4. Use: 1H-indazole-5-carbonitril is a common intermediate in organic synthesis, which can be used to prepare various indazole derivatives, such as drugs, dyes and pesticides.
Preparation Method:
1H-indazole-5-carbonitril is generally synthesized by taking an indazole compound (indazole) as a starting material and reacting it with sodium chloride (NaCl) and mercury cyanide (Hg(CN)2) in a bottom phase to produce 1H-indazole-3-carbonboxamide. Subsequently, the iminoindazole is reacted with sodium hydrocyanate (NaCN) in alcoholic solution to yield 1H-indazole-5-carbonitril.
Safety Information:
The compound should be handled in accordance with general laboratory safety procedures. For the use and disposal of chemicals and the hazards of interaction with them, reference should be made to the Safety Data Sheet (SDS) provided by the chemical manufacturer.
