Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-[4-(4-Benzylpiperazin-1-yl)phenyl]-4-chlorobenzamide.
N-[4-(4-Benzylpiperazin-1-yl)phenyl]-4-chlorobenzamide (CAS 303151-11-3) is a high-purity analytical reference standard with the molecular formula C24H24ClN3O and a molecular weight of 405.92 g/mol.
N-[4-(4-Benzylpiperazin-1-yl)phenyl]-4-chlorobenzamide (C24H24ClN3O) 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; 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.
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.
