Description
CATO supplies 1-Bromo-4-(phenylethynyl)benzene (CAS 13667-12-4), a certified reference material (molecular formula C14H9Br, MW 257.13 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-4-(phenylethynyl)benzene (C14H9Br) 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.
As a certified reference material (CRM), 1-Bromo-4-(phenylethynyl)benzene 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.
