Chemical Structure
Description
As a certified reference material (CRM), (E)-2-Phenyl-4-(thiophen-3-ylmethylene)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.
CATO supplies (E)-2-Phenyl-4-(thiophen-3-ylmethylene)oxazol-5(4H)-one (CAS 88991-47-3), a certified reference material (molecular formula C14H9NO2S, MW 255.29 g/mol) for analytical method development and quality control.
(E)-2-Phenyl-4-(thiophen-3-ylmethylene)oxazol-5(4H)-one (C14H9NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
