Chemical Structure

Thiophene-3-sulfonyl chloride CAS 51175-71-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.65 g/mol gives Thiophene-3-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Thiophene-3-sulfonyl chloride (CAS 51175-71-4), a certified reference material (molecular formula C4H3ClO2S2, MW 182.65 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Thiophene-3-sulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.65 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.

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.

CATO manufactures Thiophene-3-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
