Chemical Structure
Description
CATO supplies 4-Benzylidene-2-(p-tolyl)oxazol-5(4H)-one (CAS 16352-73-1), a certified reference material (molecular formula C35H49N5O8, MW 667.79 g/mol) for analytical method development and quality control.
The molecular framework of 4-Benzylidene-2-(p-tolyl)oxazol-5(4H)-one (C35H49N5O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Benzylidene-2-(p-tolyl)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.
