2-(Dicyclohexylphosphino)benzaldehyde CAS 226089-17-4

Description

The occurrence of 2-(Dicyclohexylphosphino)benzaldehyde is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(Dicyclohexylphosphino)benzaldehyde (CAS 226089-17-4), a certified reference material (molecular formula C19H27OP, MW 302.39 g/mol) for analytical method development and quality control.

The molecular framework of 2-(Dicyclohexylphosphino)benzaldehyde (C19H27OP) is characterized by a steroid core, 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.

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.
