Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(1-(4-Bromophenyl)-3-oxobutyl)-4-hydroxy-2H-chromen-2-one.
3-(1-(4-Bromophenyl)-3-oxobutyl)-4-hydroxy-2H-chromen-2-one (CAS 101894-60-4), molecular formula C19H15BrO4 and molecular weight 387.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(1-(4-Bromophenyl)-3-oxobutyl)-4-hydroxy-2H-chromen-2-one (C19H15BrO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. 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 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.
As a certified reference material (CRM), 3-(1-(4-Bromophenyl)-3-oxobutyl)-4-hydroxy-2H-chromen-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.
