1-(2-methoxyethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride CAS 1183972-27-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-methoxyethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride.

1-(2-methoxyethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride (CAS 1183972-27-1) is a high-purity analytical reference standard with the molecular formula C8H13ClN2O3S and a molecular weight of 252.72 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(2-methoxyethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
