5-[(4-phenoxyphenyl)amino]-1,3,4-thiadiazole-2-thiol (CAS 380431-13-0), molecular formula C14H11N3OS2 and molecular weight 301.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-[(4-phenoxyphenyl)amino]-1,3,4-thiadiazole-2-thiol (C14H11N3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 5-[(4-phenoxyphenyl)amino]-1,3,4-thiadiazole-2-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.
