Chemical Structure

8-Bromo-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-thione CAS 103845-98-3 chemical structure

Description

8-Bromo-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-thione (CAS 103845-98-3) is a high-purity analytical reference standard with the molecular formula C9H5BrN4S and a molecular weight of 281.13 g/mol.

The molecular framework of 8-Bromo-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-thione (C9H5BrN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. 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).

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 8-Bromo-2H-[1,2,4]triazino[5,6-b]indole-3(5H)-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.
