Chemical Structure

Bis(1,1-dimethylethyl)[4-methoxy-3,5,6-trimethyl-2',4',6'-tris(1-methylethyl)[1,1'-biphenyl]-2-yl]phosphine CAS 1359986-21-2 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.

Bis(1,1-dimethylethyl)[4-methoxy-3,5,6-trimethyl-2',4',6'-tris(1-methylethyl)[1,1'-biphenyl]-2-yl]phosphine (CAS 1359986-21-2) is a high-purity analytical reference standard with the molecular formula C33H53OP and a molecular weight of 496.75 g/mol.

The molecular framework of Bis(1,1-dimethylethyl)[4-methoxy-3,5,6-trimethyl-2',4',6'-tris(1-methylethyl)[1,1'-biphenyl]-2-yl]phosphine (C33H53OP) is characterized by organophosphorus functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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