5-nitro-2H-pyrazole-3-carboxylic acid methyl ester - Introduction
Acid Methyl Ester is an organic compound with the chemical formula C6H4N2O6.
Nature:
A Methyl Ester is a colorless to light yellow solid that is stable at room temperature and pressure. It is insoluble in water, but soluble in organic solvents such as ethanol, dichloromethane, etc. The compound may decompose at high temperatures, producing toxic gases.
Use:
Acid Methyl Ester is mainly used as an intermediate in organic synthesis reactions. It can be used in the preparation of amino acids, pharmaceuticals, and other organic compounds. It is also used as a component of explosives, military explosives and rocket propellants.
Method:
The preparation method of Acid Methyl Ester is usually to obtain 5-Nitro-1H-Pyrazole-3-Carboxylic Acid by nitrating aniline, and then react with methanol to form the corresponding Ester.
Safety Information:
Since Acid Methyl Ester is an explosive substance, it needs to be stored and handled properly. During operation, avoid exposure to high temperature, fire source and open flame. At the same time, protective glasses and gloves should be worn to prevent contact with skin and eyes. If the substance is accidentally inhaled or ingested, seek medical attention immediately.
