(E)-4-(2-(4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)vinyl)benzonitrile CAS 338750-92-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-(2-(4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)vinyl)benzonitrile.

(E)-4-(2-(4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)vinyl)benzonitrile (CAS 338750-92-8) is a high-purity analytical reference standard with the molecular formula C23H15N3O and a molecular weight of 349.38 g/mol.

(E)-4-(2-(4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)vinyl)benzonitrile (C23H15N3O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
