Chemical Structure
Description
3-Chloro-2-{4-[2-(4-chlorophenyl)cyclopropanecarbonyl]phenoxy}-5-(trifluoromethyl)pyridine (CAS 338401-40-4), molecular formula C22H14Cl2F3NO2 and molecular weight 452.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Chloro-2-{4-[2-(4-chlorophenyl)cyclopropanecarbonyl]phenoxy}-5-(trifluoromethyl)pyridine (C22H14Cl2F3NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 452.25 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
