CAS 133639-29-9

1H-Pyrazole-5-carbonyl chloride, 3-methyl-1-(1-methylethyl)- (9CI)

Description:

1H-Pyrazole-5-carbonyl chloride, 3-methyl-1-(1-methylethyl)-, with the CAS number 133639-29-9, is an organic compound characterized by its pyrazole ring structure, which is a five-membered aromatic heterocycle containing two nitrogen atoms. This compound features a carbonyl chloride functional group, indicating its reactivity as an acyl chloride, which can readily participate in nucleophilic acyl substitution reactions. The presence of a methyl group and an isopropyl group on the pyrazole ring contributes to its steric and electronic properties, potentially influencing its reactivity and interactions with other molecules. As an acyl chloride, it is typically used in organic synthesis for the introduction of acyl groups into various substrates. The compound is likely to be a colorless to pale yellow liquid or solid, depending on its purity and specific conditions. Due to the presence of the carbonyl chloride group, it may be sensitive to moisture and should be handled with care, as it can release hydrochloric acid upon hydrolysis.
