Chemical Structure

3-(Dicyclohexylphosphino)cyclohexanone CAS 661486-74-4 chemical structure

Description

CATO supplies 3-(Dicyclohexylphosphino)cyclohexanone (CAS 661486-74-4), a certified reference material (molecular formula C18H31OP, MW 294.41 g/mol) for analytical method development and quality control.

The molecular framework of 3-(Dicyclohexylphosphino)cyclohexanone (C18H31OP) is characterized by organophosphorus functionality, 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 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.

CATO manufactures 3-(Dicyclohexylphosphino)cyclohexanone 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.
