Chemical Structure

N,1-diphenylcyclopentane-1-carboxamide CAS 328964-72-3 chemical structure

Description

The occurrence of N,1-diphenylcyclopentane-1-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,1-diphenylcyclopentane-1-carboxamide (CAS 328964-72-3), molecular formula C18H19NO and molecular weight 265.35 g/mol, is a CATO reference standard with documented purity and traceability.

N,1-diphenylcyclopentane-1-carboxamide (C18H19NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
