Chemical Structure

2-(4-Methyl-2,3-dioxo-3,4-dihydroquinoxalin-1(2H)-yl)acetic acid CAS 1031628-34-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-(4-Methyl-2,3-dioxo-3,4-dihydroquinoxalin-1(2H)-yl)acetic acid (CAS 1031628-34-8), a certified reference material (molecular formula C11H10N2O4, MW 234.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H10N2O4, 2-(4-Methyl-2,3-dioxo-3,4-dihydroquinoxalin-1(2H)-yl)acetic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
