Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl (2E)-3-[(3,4-difluorophenyl)amino]-2-(2-fluorobenzenesulfonyl)prop-2-enoate (CAS 1327193-75-8), a certified reference material (molecular formula C16H12F3NO4S, MW 371.33 g/mol) for analytical method development and quality control.
Methyl (2E)-3-[(3,4-difluorophenyl)amino]-2-(2-fluorobenzenesulfonyl)prop-2-enoate (C16H12F3NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
