Chemical Structure
Description
CATO supplies 4-[(2E)-3-(3-Chlorophenyl)prop-2-enoyl]phenyl 4-fluorobenzene-1-sulfonate (CAS 298216-08-7), a certified reference material (molecular formula C21H14ClFO4S, MW 416.85 g/mol) for analytical method development and quality control.
4-[(2E)-3-(3-Chlorophenyl)prop-2-enoyl]phenyl 4-fluorobenzene-1-sulfonate (C21H14ClFO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
