Chemical Structure
Description
CATO supplies N-(2-Aminophenyl)furo[2,3-b]quinoxaline-3-carboxamide (CAS 93446-71-0), a certified reference material (molecular formula C17H12N4O2, MW 304.30 g/mol) for analytical method development and quality control.
N-(2-Aminophenyl)furo[2,3-b]quinoxaline-3-carboxamide (C17H12N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
