[[3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]methyl]triphenylphosphonium Chloride CAS 103929-86-8 chemical structure

Description

The occurrence of [[3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]methyl]triphenylphosphonium Chloride is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

[[3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]methyl]triphenylphosphonium Chloride (CAS 103929-86-8) is a high-purity analytical reference standard with the molecular formula C37H50O2PSi2Cl and a molecular weight of 649.40 g/mol.

Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, [[3,5-Bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]methyl]triphenylphosphonium Chloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 649.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
