7-Amino-5-chloro-2(3H)-benzoxazolone CAS 889884-60-0

Description

The occurrence of 7-Amino-5-chloro-2(3H)-benzoxazolone is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Amino-5-chloro-2(3H)-benzoxazolone (CAS 889884-60-0) is a high-purity analytical reference standard with the molecular formula C7H5ClN2O2 and a molecular weight of 184.58 g/mol.

7-Amino-5-chloro-2(3H)-benzoxazolone (C7H5ClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
