1,5-dimethyl-3-pyrazolecarboxylic acid - Introduction
1, a kind of organic compound, chemical formula is C6H8N2O2. The following is a description of its nature, use, formulation and safety information:
Nature:
1, acid is a colorless or yellowish crystal, which is soluble in water and some organic solvents. Its melting point is 173-176°C. Under alkaline conditions it dissociates to form negative ions.
Use:
1, acid is commonly used as a reagent and intermediate in organic synthesis. It has a wide range of applications in the synthesis of drugs, dyes and pesticides.
Preparation Method:
1, acid can be obtained by the reaction of pyrazole and methacrolein. First, pyrazole is subjected to an addition reaction with methacrolein in the presence of methanol to produce methylene acrolein pyrazole. Then, methyleneacrolein pyrazole undergoes oxidation and acidification reactions to obtain the target product 1, 1-oxacid.
Safety Information:
1. There are no special safety risks reported under normal use conditions. However, as an organic compound, it is still necessary to pay attention to safety precautions during operation to avoid contact with skin and eyes. It is necessary to operate in a well-ventilated laboratory environment and pay attention to fire and explosion prevention measures. The safety data sheet and relevant operating instructions should be read carefully and observed before use. In case of accidental contact or ingestion, medical help should be sought immediately.
