N-(2-Chlorophenyl)-2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2(3H)-yl)acetamide CAS 354786-13-3

Description

N-(2-Chlorophenyl)-2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2(3H)-yl)acetamide (CAS 354786-13-3), molecular formula C15H11ClN2O4S and molecular weight 350.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-(2-Chlorophenyl)-2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2(3H)-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.78 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 N-(2-Chlorophenyl)-2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2(3H)-yl)acetamide 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.
