Chemical Structure

Tris(p-tert-butylphenyl)phosphineoxide CAS 29942-35-6 chemical structure

Description

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.

Tris(p-tert-butylphenyl)phosphineoxide (CAS 29942-35-6) is a high-purity analytical reference standard with the molecular formula C30H39OP and a molecular weight of 446.60 g/mol.

The molecular framework of Tris(p-tert-butylphenyl)phosphineoxide (C30H39OP) is characterized by a steroid core, organophosphorus functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
