Chemical Structure
Description
2,6-Bis(4-bromophenyl)-4-phenylpyridine (C23H15Br2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2,6-Bis(4-bromophenyl)-4-phenylpyridine (CAS 74918-94-8), molecular formula C23H15Br2N and molecular weight 465.18 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,6-Bis(4-bromophenyl)-4-phenylpyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
