Chemical Structure
Description
The occurrence of (5Z)-3-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-(4-chlorophenyl)-5-[(2,4-dichlorophenyl)methylidene]-2,5-dihydrofuran-2-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5Z)-3-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-(4-chlorophenyl)-5-[(2,4-dichlorophenyl)methylidene]-2,5-dihydrofuran-2-one (CAS 320420-52-8), a certified reference material (molecular formula C23H10Cl4F3NO2, MW 531.14 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (5Z)-3-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-(4-chlorophenyl)-5-[(2,4-dichlorophenyl)methylidene]-2,5-dihydrofuran-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 531.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
