Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 317.81 g/mol gives 3-Chloro-4-methoxy-N-(thiophen-3-ylmethyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Chloro-4-methoxy-N-(thiophen-3-ylmethyl)benzenesulfonamide (CAS 1060310-40-8), a certified reference material (molecular formula C12H12ClNO3S2, MW 317.81 g/mol) for analytical method development and quality control.
Structurally, 3-Chloro-4-methoxy-N-(thiophen-3-ylmethyl)benzenesulfonamide (C12H12ClNO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 317.81 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
