Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(3,4-Dimethoxyphenyl)-4-phenyl-4H-1,2,4-triazole-3-thiol.
CATO supplies 5-(3,4-Dimethoxyphenyl)-4-phenyl-4H-1,2,4-triazole-3-thiol (CAS 91759-69-2), a certified reference material (molecular formula C16H15N3O2S, MW 313.37 g/mol) for analytical method development and quality control.
5-(3,4-Dimethoxyphenyl)-4-phenyl-4H-1,2,4-triazole-3-thiol (C16H15N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 5-(3,4-Dimethoxyphenyl)-4-phenyl-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.
