Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
3-Phenyl-5-[(E)-2-(phenylamino)ethenyl]-1,2-oxazole-4-carbonitrile (CAS 338992-50-0) is a high-purity analytical reference standard with the molecular formula C18H13N3O and a molecular weight of 287.32 g/mol.
3-Phenyl-5-[(E)-2-(phenylamino)ethenyl]-1,2-oxazole-4-carbonitrile (C18H13N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
