Chemical Structure

Tris(2,4-di-tert-butylphenyl)phosphane CAS 130600-71-4 chemical structure

Description

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 supplies Tris(2,4-di-tert-butylphenyl)phosphane (CAS 130600-71-4), a certified reference material (molecular formula C42H63P, MW 598.92 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, a polycyclic aromatic system, Tris(2,4-di-tert-butylphenyl)phosphane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 598.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
