Chemical Structure

2-((1S,4S)-4-(4-chlorophenylsulfonyl)-4-(2,5-difluorophenyl)cyclohexyl)acetaldehyde CAS 656810-85-4 chemical structure

Description

The occurrence of 2-((1S,4S)-4-(4-chlorophenylsulfonyl)-4-(2,5-difluorophenyl)cyclohexyl)acetaldehyde is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-((1S,4S)-4-(4-chlorophenylsulfonyl)-4-(2,5-difluorophenyl)cyclohexyl)acetaldehyde (CAS 656810-85-4), a certified reference material (molecular formula C20H19ClF2O3S, MW 412.88 g/mol) for analytical method development and quality control.

The molecular framework of 2-((1S,4S)-4-(4-chlorophenylsulfonyl)-4-(2,5-difluorophenyl)cyclohexyl)acetaldehyde (C20H19ClF2O3S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 2-((1S,4S)-4-(4-chlorophenylsulfonyl)-4-(2,5-difluorophenyl)cyclohexyl)acetaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
