Nature:
4-amino-3,5-dimethyl-pyrazol is a white to pale yellow crystalline solid. It has high stability at room temperature and is soluble in some organic solvents, such as ethanol and dimethylformamide.

Use:
4-amino-3,5-dimethyl-pyrazol is a common organic synthesis intermediate. It can be used to synthesize a variety of organic compounds, such as drugs, dyes and pesticides. Because its structure contains pyrazole and amine groups, it has important application potential in the field of drug research and development.

Preparation Method:
The method for preparing 4-amino-3,5-dimethyl-pyrazol can be obtained by the ortho-methylation reaction of pyrazole. First, pyrazole is reacted with a methylating agent such as methyl iodide or methyl bromide to produce 3-methylpyrazole. The 3-methylpyrazole is then reacted with ammonia to obtain the target product 4-amino-3,5-dimethyl-pyrazol.

Safety Information:
4-amino-3,5-dimethyl-pyrazol can be safely handled under correct use. However, during the operation, it is still necessary to pay attention to the safe operation of the chemical laboratory, such as wearing appropriate protective equipment (such as gloves and goggles), avoiding direct contact with the skin and eyes, and avoiding inhalation or ingestion.
