2-(2-(2-Chlorophenyl)-4-oxoquinazolin-3(4H)-yl)ethyl 2-nitrobenzoate CAS 90094-96-5

Description

The occurrence of 2-(2-(2-Chlorophenyl)-4-oxoquinazolin-3(4H)-yl)ethyl 2-nitrobenzoate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(2-(2-Chlorophenyl)-4-oxoquinazolin-3(4H)-yl)ethyl 2-nitrobenzoate (CAS 90094-96-5) is a high-purity analytical reference standard with the molecular formula C23H16ClN3O5 and a molecular weight of 449.84 g/mol.

The molecular framework of 2-(2-(2-Chlorophenyl)-4-oxoquinazolin-3(4H)-yl)ethyl 2-nitrobenzoate (C23H16ClN3O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
