(E)-4-((3,5-dibromo-2,4-dihydroxybenzylidene)amino)-5-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione CAS 468755-27-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-((3,5-dibromo-2,4-dihydroxybenzylidene)amino)-5-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione.

(E)-4-((3,5-dibromo-2,4-dihydroxybenzylidene)amino)-5-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 468755-27-3) is a high-purity analytical reference standard with the molecular formula C10H8Br2N4O2S and a molecular weight of 408.07 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, (E)-4-((3,5-dibromo-2,4-dihydroxybenzylidene)amino)-5-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (E)-4-((3,5-dibromo-2,4-dihydroxybenzylidene)amino)-5-methyl-2,4-dihydro-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.
