Chemical Structure

Trioctylphosphine selenide CAS 20612-73-1 chemical structure

Description

CATO supplies Trioctylphosphine selenide (CAS 20612-73-1), a certified reference material (molecular formula C24H51PSe, MW 449.60 g/mol) for analytical method development and quality control.

The molecular framework of Trioctylphosphine selenide (C24H51PSe) is characterized by organophosphorus functionality. 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.

CATO manufactures Trioctylphosphine selenide 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.
