N-(3-chloro-4-methylphenyl)-2-(4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)phenyl)acetamide (CAS 866017-70-1), molecular formula C21H15Cl2F3N2O2 and molecular weight 455.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(3-chloro-4-methylphenyl)-2-(4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)phenyl)acetamide (C21H15Cl2F3N2O2) 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 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 455.26 g/mol, it falls into the moderately-high-molecular-weight range. 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.
