Chemical Structure
Description
4-(4,4-Bis(4-fluorophenyl)butyl)-N-ethylpiperazine-1-carboxamide (CAS 75529-73-6) is a high-purity analytical reference standard with the molecular formula C23H29F2N3OHCl and a molecular weight of 437.96 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-(4,4-Bis(4-fluorophenyl)butyl)-N-ethylpiperazine-1-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
