Description
CATO supplies 4-Chloro-N-(1-(4-ethyl-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide (CAS 338954-01-1), a certified reference material (molecular formula C19H20ClFN4O2S2, MW 454.97 g/mol) for analytical method development and quality control.
4-Chloro-N-(1-(4-ethyl-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide (C19H20ClFN4O2S2) 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).
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 4-Chloro-N-(1-(4-ethyl-5-((3-fluorobenzyl)thio)-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide 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.
