methyl 5-ethyl-1H-pyrazole-3-carboxylate - Introduction
Methyl is an organic compound with a molecular formula of C8H10N2O2 and a molecular weight of 166.18g/mol. The following is a description of its nature, use, preparation and safety information:
Nature:
Methyl is a colorless liquid with a special smell. It has a boiling point of 248-250°C and a density of 1.14 g/mL. It has good solubility in dissolved organic solvents (such as ethanol, dichloromethane, etc.).
Use:
Methyl can be used as an important intermediate in organic synthesis. It has a wide range of applications in the field of pesticides, pharmaceuticals and cosmetics. It can be used in the synthesis of compounds with pharmacological activity and is commonly used as a raw material for the synthesis of anti-inflammatory, antibacterial and antitumor drugs.
Preparation Method:
The preparation of Methyl can be achieved by ethylation of pyrazole-5-carboxylic acid. The specific method is to react pyrazole-5-carboxylic acid with alkali (such as sodium hydroxide) to generate the corresponding pyrazole-5-acid salt, and add ethyl halide (such as ethyl bromide compound) for esterification reaction, and then obtain Methyl.
Safety Information:
Methyl is relatively safe under the correct use and storage, but still need to pay attention to safety measures. It is a flammable liquid and should avoid contact with open flames and strong oxidants. During operation, it is recommended to wear appropriate protective gloves, safety glasses and protective clothing. When in contact with the skin or eyes should immediately rinse with plenty of water. If inhaled or ingested, seek medical attention immediately. When stored, should be away from fire and heat sources, stored in a cool, dry, ventilated place.
