Chemical Structure
Description
CATO supplies N-{4-[4-(4-fluorophenyl)piperazin-1-yl]phenyl}pentanamide (CAS 303151-20-4), a certified reference material (molecular formula C21H26FN3O, MW 355.45 g/mol) for analytical method development and quality control.
Structurally, N-{4-[4-(4-fluorophenyl)piperazin-1-yl]phenyl}pentanamide (C21H26FN3O) 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 355.45 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
