Chemical Structure

n-Phenyl-2-(piperidin-4-yl)azepane-1-carboxamide CAS 1334148-71-8 chemical structure

Description

n-Phenyl-2-(piperidin-4-yl)azepane-1-carboxamide (CAS 1334148-71-8), molecular formula C18H27N3O and molecular weight 301.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-Phenyl-2-(piperidin-4-yl)azepane-1-carboxamide (C18H27N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
