Description
As a certified reference material (CRM), 1-(2-Bromo-4-hydroxyphenyl)ethanone 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.
1-(2-Bromo-4-hydroxyphenyl)ethanone (CAS 61791-99-9), molecular formula C8H7BrO2 and molecular weight 215.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Bromo-4-hydroxyphenyl)ethanone (C8H7BrO2) 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 the polarity and ionization state of its functional groups, 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.
