Chemical Structure

4-Fluoro-N-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide CAS 923871-23-2 chemical structure

Description

4-Fluoro-N-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide (CAS 923871-23-2), molecular formula C12H12FNO2S2 and molecular weight 285.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-Fluoro-N-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 4-Fluoro-N-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide 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.
