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 Ethyl 2-bromo-3-(4-bromophenyl)-3-oxopropanoate.
Ethyl 2-bromo-3-(4-bromophenyl)-3-oxopropanoate (CAS 87943-97-3), molecular formula C11H10Br2O3 and molecular weight 350.00 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H10Br2O3, Ethyl 2-bromo-3-(4-bromophenyl)-3-oxopropanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Ethyl 2-bromo-3-(4-bromophenyl)-3-oxopropanoate 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.
