Chemical Structure
Description
The occurrence of (E)-2-(2-(furan-2-yl)vinyl)-3-phenylquinazolin-4(3H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(2-(furan-2-yl)vinyl)-3-phenylquinazolin-4(3H)-one (CAS 71822-45-2) is a high-purity analytical reference standard with the molecular formula C20H14N2O2 and a molecular weight of 314.34 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (E)-2-(2-(furan-2-yl)vinyl)-3-phenylquinazolin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
