Chemical Structure

Octadecylphosphophosphoniumcholine CAS 156825-89-7 chemical structure

Description

CATO manufactures Octadecylphosphophosphoniumcholine 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.

CATO supplies Octadecylphosphophosphoniumcholine (CAS 156825-89-7), a certified reference material (molecular formula C23H50O4P2, MW 452.59 g/mol) for analytical method development and quality control.

The molecular framework of Octadecylphosphophosphoniumcholine (C23H50O4P2) is characterized by a phosphate ester group, a carboxylic acid group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
