Bis(2,4-di-tert-butylphenyl) phenylphosphonite CAS 70146-21-3

Description

Compared with other compounds in its class, the molecular weight of 517.70 g/mol gives Bis(2,4-di-tert-butylphenyl) phenylphosphonite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(2,4-di-tert-butylphenyl) phenylphosphonite (CAS 70146-21-3), a certified reference material (molecular formula C34H46O2P, MW 517.70 g/mol) for analytical method development and quality control.

The molecular framework of Bis(2,4-di-tert-butylphenyl) phenylphosphonite (C34H46O2P) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Bis(2,4-di-tert-butylphenyl) phenylphosphonite 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.
