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 3-((4-Chlorobenzyl)thio)-5-(((2,6-dichlorobenzyl)sulfinyl)methyl)-4-methyl-4H-1,2,4-triazole.
3-((4-Chlorobenzyl)thio)-5-(((2,6-dichlorobenzyl)sulfinyl)methyl)-4-methyl-4H-1,2,4-triazole (CAS 344271-72-3), molecular formula C18H16Cl3N3OS2 and molecular weight 460.83 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-((4-Chlorobenzyl)thio)-5-(((2,6-dichlorobenzyl)sulfinyl)methyl)-4-methyl-4H-1,2,4-triazole (C18H16Cl3N3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 460.83 g/mol, it falls into the moderately-high-molecular-weight range. 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 3-((4-Chlorobenzyl)thio)-5-(((2,6-dichlorobenzyl)sulfinyl)methyl)-4-methyl-4H-1,2,4-triazole 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.
