Chemical Structure
Description
(Z)-4-(2-methoxybenzylidene)-2-phenyloxazol-5(4h)-one (CAS 57427-84-6) is a high-purity analytical reference standard with the molecular formula C17H13NO3 and a molecular weight of 279.29 g/mol.
The molecular framework of (Z)-4-(2-methoxybenzylidene)-2-phenyloxazol-5(4h)-one (C17H13NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
