Chemical Structure
Description
2-Chloro-4-(2-N,N-dimethylsulfamoylphenyl)benzoic acid (CAS 1261939-26-7) is a high-purity analytical reference standard with the molecular formula C15H14ClNO4S and a molecular weight of 339.79 g/mol.
2-Chloro-4-(2-N,N-dimethylsulfamoylphenyl)benzoic acid (C15H14ClNO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
CATO manufactures 2-Chloro-4-(2-N,N-dimethylsulfamoylphenyl)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.
