Chemical Structure
Description
2,5-Dichloro-N-(4-(N-(thiazol-2-yl)sulfamoyl)phenyl)thiophene-3-carboxamide (CAS 314259-41-1), molecular formula C14H9Cl2N3O3S3 and molecular weight 434.34 g/mol, is a CATO reference standard with documented purity and traceability.
2,5-Dichloro-N-(4-(N-(thiazol-2-yl)sulfamoyl)phenyl)thiophene-3-carboxamide (C14H9Cl2N3O3S3) 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).
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 2,5-Dichloro-N-(4-(N-(thiazol-2-yl)sulfamoyl)phenyl)thiophene-3-carboxamide 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.
