Chemical Structure
Description
The occurrence of Methyl 3-{[2-nitro-2-(phenylsulfonyl)vinyl]amino}benzenecarboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 3-{[2-nitro-2-(phenylsulfonyl)vinyl]amino}benzenecarboxylate (CAS 477864-69-0), a certified reference material (molecular formula C16H14N2O6S, MW 362.36 g/mol) for analytical method development and quality control.
Methyl 3-{[2-nitro-2-(phenylsulfonyl)vinyl]amino}benzenecarboxylate (C16H14N2O6S) contains a flavonoid core, an amide group, a sulfone 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.
