3-Methylquinoxaline-5,7-diamine CAS 90558-60-4 chemical structure

Description

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.

CATO supplies 3-Methylquinoxaline-5,7-diamine (CAS 90558-60-4), a certified reference material (molecular formula C9H10N4, MW 174.20 g/mol) for analytical method development and quality control.

3-Methylquinoxaline-5,7-diamine (C9H10N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; 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.
