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 supplies 2-Chloro-N-((4-(5-chlorobenzo[d]oxazol-2-yl)phenyl)carbamothioyl)-4-fluorobenzamide (CAS 593238-84-7), a certified reference material (molecular formula C21H12Cl2FN3O2S, MW 460.31 g/mol) for analytical method development and quality control.
2-Chloro-N-((4-(5-chlorobenzo[d]oxazol-2-yl)phenyl)carbamothioyl)-4-fluorobenzamide (C21H12Cl2FN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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).
CATO manufactures 2-Chloro-N-((4-(5-chlorobenzo[d]oxazol-2-yl)phenyl)carbamothioyl)-4-fluorobenzamide 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.
