Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Benzo[4,5]oxazolo[2,3-c][1,2,4]triazole-3(2H)-thione (CAS 92382-89-3) is a high-purity analytical reference standard with the molecular formula C8H5N3OS and a molecular weight of 191.21 g/mol.
The molecular framework of Benzo[4,5]oxazolo[2,3-c][1,2,4]triazole-3(2H)-thione (C8H5N3OS) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Benzo[4,5]oxazolo[2,3-c][1,2,4]triazole-3(2H)-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.
