(5-Amino-2H-pyrazol-3-yl)-acetic acid - Introduction
acetic acid (acid) is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-acetic acid is a white crystalline solid with the chemical formula c4h5no2. It is a pyrazole compound with hygroscopicity. It is slightly soluble in water, soluble in acid and alkali solutions. Its melting point is about 240-242°C.
Use:
-acetic acid is widely used as a synthetic intermediate in organic synthesis. It can be used to synthesize compounds such as pesticides, pharmaceuticals and bioactive molecules. In addition, it can also be used in the synthesis of organic dyes and metal complexes.
Method:
-acetic acid can be prepared by the following methods:
First, pyrazole is added to bromoacetic acid solution to react to generate 5-bromo-1h-pyrazole-3-acetic acid;
Then, 5-bromo-1h-pyrazole-3-acetic acid is reacted with ammonia to generate ()-acetic acid.
Safety Information:
When operating, you should pay attention to the protective measures of-acetic acid. It may be irritating to the eyes and skin, so direct contact should be avoided when in contact. Wear suitable protective glasses and gloves when using. In addition, it should also be stored in a dry and ventilated place to avoid contact with oxidants and reducing agents to avoid dangerous reactions.
