Description
As a certified reference material (CRM), 8-Bromo-5-phenyl-5H-pyrido[4,3-b]indole 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.
8-Bromo-5-phenyl-5H-pyrido[4,3-b]indole (CAS 1303503-70-9) is a high-purity analytical reference standard with the molecular formula C17H11BrN2 and a molecular weight of 323.19 g/mol.
The molecular framework of 8-Bromo-5-phenyl-5H-pyrido[4,3-b]indole (C17H11BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
