Chemical Structure
Description
(2E)-1-(4-Bromophenyl)-3-(4-methoxyphenyl)prop-2-en-1-one (CAS 51863-81-1), molecular formula C16H13BrO2 and molecular weight 317.18 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-1-(4-Bromophenyl)-3-(4-methoxyphenyl)prop-2-en-1-one (C16H13BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (2E)-1-(4-Bromophenyl)-3-(4-methoxyphenyl)prop-2-en-1-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.
