1-Ethyl-3-(trifluoromethyl)-1h-pyrazole-5-sulfonyl chloride CAS 1245823-96-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-3-(trifluoromethyl)-1h-pyrazole-5-sulfonyl chloride.

1-Ethyl-3-(trifluoromethyl)-1h-pyrazole-5-sulfonyl chloride (CAS 1245823-96-4) is a high-purity analytical reference standard with the molecular formula C6H6ClF3N2O2S and a molecular weight of 262.64 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1-Ethyl-3-(trifluoromethyl)-1h-pyrazole-5-sulfonyl chloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
