Description
Compared with other compounds in its class, the molecular weight of 347.39 g/mol gives 2-({2-[(3,4-dimethoxyphenyl)amino]-2-oxoethyl}thio)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-({2-[(3,4-dimethoxyphenyl)amino]-2-oxoethyl}thio)benzoic acid (CAS 440347-44-4), a certified reference material (molecular formula C17H17NO5S, MW 347.39 g/mol) for analytical method development and quality control.
2-({2-[(3,4-dimethoxyphenyl)amino]-2-oxoethyl}thio)benzoic acid (C17H17NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
