Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-[3-(4-Fluorophenyl)acryloyl]phenyl 4-methylbenzenecarboxylate (CAS 329704-19-0), molecular formula C23H17FO3 and molecular weight 360.38 g/mol, is a CATO reference standard with documented purity and traceability.
4-[3-(4-Fluorophenyl)acryloyl]phenyl 4-methylbenzenecarboxylate (C23H17FO3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine 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).
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.
