2-chloro-4,5-difluorobenzene-1-sulfonyl chloride CAS 67475-58-5

Description

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-chloro-4,5-difluorobenzene-1-sulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.09 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.

2-chloro-4,5-difluorobenzene-1-sulfonyl chloride (CAS 67475-58-5), molecular formula C6H8Cl2F2O2S and molecular weight 253.09 g/mol, is a CATO reference standard with documented purity and traceability.

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.
