Chemical Structure
Description
The molecular framework of 2-Ethoxy-5-(3-methyl-4-nitrobenzamido)benzenesulfonyl chloride (C16H15ClN2O6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2-Ethoxy-5-(3-methyl-4-nitrobenzamido)benzenesulfonyl chloride (CAS 680618-07-9), a certified reference material (molecular formula C16H15ClN2O6S, MW 398.82 g/mol) for analytical method development and quality control.
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.
