Chemical Structure
Description
As a certified reference material (CRM), 2-Bromotriphenylene 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.
CATO supplies 2-Bromotriphenylene (CAS 19111-87-6), a certified reference material (molecular formula C18H11Br, MW 307.18 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromotriphenylene (C18H11Br) is characterized by bromine substitution, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
