Description
CATO manufactures 4,7-dibromo-1H-1,3-benzodiazole 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.
4,7-dibromo-1H-1,3-benzodiazole (CAS 148185-66-4) is a high-purity analytical reference standard with the molecular formula C7H12Br2N2 and a molecular weight of 283.99 g/mol.
4,7-dibromo-1H-1,3-benzodiazole (C7H12Br2N2) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
