2-(7-Chloro-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-yl)benzoic acid CAS 860787-85-5 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 2-(7-Chloro-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-yl)benzoic acid.

CATO supplies 2-(7-Chloro-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-yl)benzoic acid (CAS 860787-85-5), a certified reference material (molecular formula C15H9ClN2O4, MW 316.70 g/mol) for analytical method development and quality control.

Structurally, 2-(7-Chloro-3-hydroxy-4-oxo-3,4-dihydroquinazolin-2-yl)benzoic acid (C15H9ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 316.70 g/mol, it falls into the moderately-high-molecular-weight range. 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.
