Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1-(2,4-dichlorophenyl)-3-{5-[2-(trifluoromethoxy)phenyl]-2-furyl}prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 427.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-(2,4-dichlorophenyl)-3-{5-[2-(trifluoromethoxy)phenyl]-2-furyl}prop-2-en-1-one (CAS 259196-59-3), molecular formula C20H11Cl2F3O3 and molecular weight 427.20 g/mol, is a CATO reference standard with documented purity and traceability.
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.
