Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3-[(5-Mercapto-4-methyl-4H-1,2,4-triazol-3-yl)methyl]-1,3-benzothiazol-2(3H)-one (CAS 390748-27-3) is a high-purity analytical reference standard with the molecular formula C11H10N4OS2 and a molecular weight of 278.35 g/mol.

The molecular framework of 3-[(5-Mercapto-4-methyl-4H-1,2,4-triazol-3-yl)methyl]-1,3-benzothiazol-2(3H)-one (C11H10N4OS2) 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 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).

CATO manufactures 3-[(5-Mercapto-4-methyl-4H-1,2,4-triazol-3-yl)methyl]-1,3-benzothiazol-2(3H)-one 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.
