Chemical Structure
Description
The occurrence of 4,5-Dimethoxy-2-(methylsulfonamido)benzoic Acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,5-Dimethoxy-2-(methylsulfonamido)benzoic Acid (CAS 926239-35-2), a certified reference material (molecular formula C10H13NO6S, MW 275.28 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dimethoxy-2-(methylsulfonamido)benzoic Acid (C10H13NO6S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 4,5-Dimethoxy-2-(methylsulfonamido)benzoic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
