Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-(4-Bromophenyl)-7-oxoheptanoic acid (CAS 898787-83-2), a certified reference material (molecular formula C13H15BrO3, MW 299.16 g/mol) for analytical method development and quality control.
The molecular framework of 7-(4-Bromophenyl)-7-oxoheptanoic acid (C13H15BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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).
As a certified reference material (CRM), 7-(4-Bromophenyl)-7-oxoheptanoic acid 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.
