Chemical Structure

Methyl(2,4,6-tri-tert-butylphenyl)phosphine oxide CAS 88765-95-1 chemical structure

Description

Based on its molecular formula C19H33OP, Methyl(2,4,6-tri-tert-butylphenyl)phosphine oxide contains organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Methyl(2,4,6-tri-tert-butylphenyl)phosphine oxide (CAS 88765-95-1), molecular formula C19H33OP and molecular weight 308.44 g/mol, is a CATO reference standard with documented purity and traceability.

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

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.
