Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-(1-(5-((2-chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide.
CATO supplies 4-Chloro-N-(1-(5-((2-chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide (CAS 338954-02-2), a certified reference material (molecular formula C19H20Cl2N4O2S2, MW 471.42 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-N-(1-(5-((2-chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)ethyl)benzenesulfonamide (C19H20Cl2N4O2S2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
