Chemical Structure
Description
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.
3-(azepane-1-sulfonyl)-N-(3-bromophenyl)benzamide (CAS 420831-40-9), molecular formula C19H21BrN2O3S and molecular weight 437.35 g/mol, is a CATO reference standard with documented purity and traceability.
3-(azepane-1-sulfonyl)-N-(3-bromophenyl)benzamide (C19H21BrN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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).
CATO manufactures 3-(azepane-1-sulfonyl)-N-(3-bromophenyl)benzamide 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.
