Chemical Structure
Description
The occurrence of 1-Bromo-3-(4-bromophenyl)propan-2-one is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Bromo-3-(4-bromophenyl)propan-2-one (CAS 20772-10-5), a certified reference material (molecular formula C9H8Br2O, MW 291.97 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-3-(4-bromophenyl)propan-2-one (C9H8Br2O) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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-3-(4-bromophenyl)propan-2-one 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.
