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.
CATO supplies N-(3,4-Difluorophenyl)-2-{4-[3-(trifluoromethyl)phenyl]piperazin-1-yl}acetamide (CAS 303091-73-8), a certified reference material (molecular formula C19H18F5N3O, MW 399.36 g/mol) for analytical method development and quality control.
Structurally, N-(3,4-Difluorophenyl)-2-{4-[3-(trifluoromethyl)phenyl]piperazin-1-yl}acetamide (C19H18F5N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 399.36 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.
