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 5-{3-[(2,4-dichlorobenzyl)oxy]-2-thienyl}-4-methyl-4H-1,2,4-triazole-3-thiol.
5-{3-[(2,4-dichlorobenzyl)oxy]-2-thienyl}-4-methyl-4H-1,2,4-triazole-3-thiol (CAS 343375-92-8), molecular formula C14H11Cl2N3OS2 and molecular weight 372.29 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-{3-[(2,4-dichlorobenzyl)oxy]-2-thienyl}-4-methyl-4H-1,2,4-triazole-3-thiol (C14H11Cl2N3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 372.29 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 5-{3-[(2,4-dichlorobenzyl)oxy]-2-thienyl}-4-methyl-4H-1,2,4-triazole-3-thiol 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.
