Chemical Structure
Description
As a certified reference material (CRM), (Z)-4-benzylidene-2-phenyloxazol-5(4H)-one 17606-70-1 4-Benzal-2-phenyl-5-oxazolone 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.
(Z)-4-benzylidene-2-phenyloxazol-5(4H)-one 17606-70-1 4-Benzal-2-phenyl-5-oxazolone (CAS 17606-70-1), molecular formula C16H11NO2 and molecular weight 249.26 g/mol, is a CATO reference standard with documented purity and traceability.
(Z)-4-benzylidene-2-phenyloxazol-5(4H)-one 17606-70-1 4-Benzal-2-phenyl-5-oxazolone (C16H11NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
