Chemical Structure
Description
CATO supplies 2-(Hydroxy(phenyl)carbamoyl)benzenesulfonic acid (CAS 38238-21-0), a certified reference material (molecular formula C13H11NO5S, MW 293.30 g/mol) for analytical method development and quality control.
2-(Hydroxy(phenyl)carbamoyl)benzenesulfonic acid (C13H11NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-(Hydroxy(phenyl)carbamoyl)benzenesulfonic 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.
