Chemical Structure

(2,4,6-Tri-tert-butylphenyl)phosphine CAS 83115-12-2 chemical structure

Description

Structurally, (2,4,6-Tri-tert-butylphenyl)phosphine (C18H31P) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 278.41 g/mol, it falls into the medium-molecular-weight range. 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).

CATO supplies (2,4,6-Tri-tert-butylphenyl)phosphine (CAS 83115-12-2), a certified reference material (molecular formula C18H31P, MW 278.41 g/mol) for analytical method development and quality control.

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.
