Chemical Structure
Description
2,6-dibromo-1,3-benzothiazole (CAS 408328-13-2) is a high-purity analytical reference standard with the molecular formula C7H3Br2NS and a molecular weight of 292.98 g/mol.
The molecular framework of 2,6-dibromo-1,3-benzothiazole (C7H3Br2NS) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2,6-dibromo-1,3-benzothiazole 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.
