Chemical Structure
Description
The occurrence of 3-(5-(2,3-Dichlorophenyl)furan-2-yl)-2-phenylacrylonitrile is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(5-(2,3-Dichlorophenyl)furan-2-yl)-2-phenylacrylonitrile (CAS 304896-40-0), molecular formula C19H11Cl2NO and molecular weight 340.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-(5-(2,3-Dichlorophenyl)furan-2-yl)-2-phenylacrylonitrile (C19H11Cl2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
