2,2,4,4-tetramethyl-6,6-diphenyl-1,3,5,2,4,6-trioxatrisilinane CAS 1693-51-2

Description

The occurrence of 2,2,4,4-tetramethyl-6,6-diphenyl-1,3,5,2,4,6-trioxatrisilinane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2,4,4-tetramethyl-6,6-diphenyl-1,3,5,2,4,6-trioxatrisilinane (CAS 1693-51-2), a certified reference material (molecular formula C16H22O3Si3, MW 346.60 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,2,4,4-tetramethyl-6,6-diphenyl-1,3,5,2,4,6-trioxatrisilinane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
