Chemical Structure
Description
The occurrence of 2-(2-Bromophenyl)-4-(4-methylbenzylidene)oxazol-5(4H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2-Bromophenyl)-4-(4-methylbenzylidene)oxazol-5(4H)-one (CAS 84156-17-2), molecular formula C17H12BrNO2 and molecular weight 342.19 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Bromophenyl)-4-(4-methylbenzylidene)oxazol-5(4H)-one (C17H12BrNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-(2-Bromophenyl)-4-(4-methylbenzylidene)oxazol-5(4H)-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.
