Chemical Structure

Azepan-1-yl(1-(phenylsulfonyl)piperidin-4-yl)methanone CAS 478041-48-4 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 Azepan-1-yl(1-(phenylsulfonyl)piperidin-4-yl)methanone.

Azepan-1-yl(1-(phenylsulfonyl)piperidin-4-yl)methanone (CAS 478041-48-4), molecular formula C18H26N2O3S and molecular weight 350.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Azepan-1-yl(1-(phenylsulfonyl)piperidin-4-yl)methanone (C18H26N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 350.48 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
