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 4-Amino-N-(quinoxalin-2-yl)benzenesulfonamide mixt. with 4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-chromen-2-one (CAS 37341-99-4), a certified reference material (molecular formula C19H16O4C14H12N4O2S, MW 608.67 g/mol) for analytical method development and quality control.
The molecular framework of 4-Amino-N-(quinoxalin-2-yl)benzenesulfonamide mixt. with 4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-chromen-2-one (C19H16O4C14H12N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
