4-((3,4-Dimethoxy-N-methylphenyl)sulfonamido)benzoic acid CAS 723247-01-6 chemical structure

Description

CATO manufactures 4-((3,4-Dimethoxy-N-methylphenyl)sulfonamido)benzoic acid 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.

4-((3,4-Dimethoxy-N-methylphenyl)sulfonamido)benzoic acid (CAS 723247-01-6) is a high-purity analytical reference standard with the molecular formula C16H17NO6S and a molecular weight of 351.37 g/mol.

Based on its molecular formula C16H17NO6S, 4-((3,4-Dimethoxy-N-methylphenyl)sulfonamido)benzoic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
