CATO supplies 4-chloro-N'-(4,5-dihydronaphtho[1,2-b]thiophen-2-ylcarbonyl)benzenesulfonohydrazide 477888-02-1 KS-000034L1 (CAS 477888-02-1), a certified reference material (molecular formula C19H15ClN2O3S2, MW 418.92 g/mol) for analytical method development and quality control.
The molecular framework of 4-chloro-N'-(4,5-dihydronaphtho[1,2-b]thiophen-2-ylcarbonyl)benzenesulfonohydrazide 477888-02-1 KS-000034L1 (C19H15ClN2O3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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'-(4,5-dihydronaphtho[1,2-b]thiophen-2-ylcarbonyl)benzenesulfonohydrazide 477888-02-1 KS-000034L1 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.
