1-ETHYL-3-METHYL-1H-PYRAZOLE-5-CARBONYL CHLORIDE

Description:
1-Ethyl-3-methyl-1H-pyrazole-5-carbonyl chloride, with the CAS number 128249-59-2, is a chemical compound characterized by its pyrazole ring structure, which is a five-membered heterocyclic compound containing two nitrogen atoms. This compound features an ethyl group and a methyl group attached to the pyrazole ring, contributing to its unique properties. The carbonyl chloride functional group indicates the presence of a carbonyl (C=O) bonded to a chlorine atom, making it a reactive acyl chloride. This reactivity allows it to participate in various chemical reactions, such as acylation and nucleophilic substitution. The compound is typically used in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It is important to handle this substance with care due to its potential reactivity and the presence of chlorine, which can pose health and environmental risks. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this compound.
