Introduction
Indazole is a nitrogen-containing aromatic compound with the chemical formula C7H6N2. It is a white crystalline solid, soluble in alcohols and ketone solvents, slightly soluble in water. Indazole has low toxicity.Indazole has a wide range of applications. In addition, indazole is used as an additive for dyes, coatings, plastics, and rubber, as well as as a photochemical catalyst, among others.There are several ways to prepare indazole. The most common method is to react pyrazole with formaldehyde at high temperature through pyrazole thermal synthesis. Indazole can also be synthesized by methods such as amination reaction and debromination of brominated indazole.Regarding the safety of indazole, it is a low-toxicity compound, but it still needs to be handled with caution. Exposure to indazole may cause eye and skin irritation, so appropriate personal protective equipment should be worn during exposure. A well-ventilated environment should be used in the laboratory and the inhalation of its dust should be avoided. When indazole is ingested in large amounts, it may have effects on the central nervous system and should be avoided.
