5-Methyl-3H-1,2,4-triazole-3-thione (CAS 5803-95-2) is a high-purity analytical reference standard with the molecular formula C3H3N3S and a molecular weight of 113.14 g/mol.
The molecular framework of 5-Methyl-3H-1,2,4-triazole-3-thione (C3H3N3S) is characterized by a nitrile group, sulfur-containing functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 5-Methyl-3H-1,2,4-triazole-3-thione 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.
