2-(6-Chloro-4-oxoquinazolin-3(4H)-yl)acetic acid CAS 83798-86-1

Description

The occurrence of 2-(6-Chloro-4-oxoquinazolin-3(4H)-yl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, 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-(6-Chloro-4-oxoquinazolin-3(4H)-yl)acetic acid (CAS 83798-86-1) is a high-purity analytical reference standard with the molecular formula C10H7ClN2O3 and a molecular weight of 238.63 g/mol.

2-(6-Chloro-4-oxoquinazolin-3(4H)-yl)acetic acid (C10H7ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
