Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 6,6'-Dibromo-9,9'-diphenyl-3,3'-bicarbazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 642.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
6,6'-Dibromo-9,9'-diphenyl-3,3'-bicarbazole (CAS 354135-75-4), molecular formula C36H22Br2N2 and molecular weight 642.38 g/mol, is a CATO reference standard with documented purity and traceability.
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 6,6'-Dibromo-9,9'-diphenyl-3,3'-bicarbazole 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.
