(4-Chlorophenyl)(4-hydroxy-4-(((4-methoxyphenyl)thio)methyl)piperidin-1-yl)methanone CAS 866143-81-9 chemical structure

Description

The occurrence of (4-Chlorophenyl)(4-hydroxy-4-(((4-methoxyphenyl)thio)methyl)piperidin-1-yl)methanone is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (4-Chlorophenyl)(4-hydroxy-4-(((4-methoxyphenyl)thio)methyl)piperidin-1-yl)methanone (CAS 866143-81-9), a certified reference material (molecular formula C20H22ClNO3S, MW 391.91 g/mol) for analytical method development and quality control.

Structurally, (4-Chlorophenyl)(4-hydroxy-4-(((4-methoxyphenyl)thio)methyl)piperidin-1-yl)methanone (C20H22ClNO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 391.91 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
