Chemical Structure
Description
3-(4-Chlorophenyl)-4-(4-methoxybenzoyl)-1-phenylpyrrolidine (C24H22ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-(4-Chlorophenyl)-4-(4-methoxybenzoyl)-1-phenylpyrrolidine (CAS 551921-54-1) is a high-purity analytical reference standard with the molecular formula C24H22ClNO2 and a molecular weight of 391.89 g/mol.
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.
