Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.74 g/mol gives 5-[(2-chlorophenyl)sulfamoyl]-2-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-[(2-chlorophenyl)sulfamoyl]-2-hydroxybenzoic acid (CAS 62547-09-5), molecular formula C13H10ClNO5S and molecular weight 327.74 g/mol, is a CATO reference standard with documented purity and traceability.
5-[(2-chlorophenyl)sulfamoyl]-2-hydroxybenzoic acid (C13H10ClNO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
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.
