Chemical Structure

2,2,4,4,6,6-Hexakis(hexadecyl)-1,3,5,2,4,6-trioxatrisilinane CAS 139231-91-7 chemical structure

Description

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.

2,2,4,4,6,6-Hexakis(hexadecyl)-1,3,5,2,4,6-trioxatrisilinane (CAS 139231-91-7), molecular formula C96H198O3Si3 and molecular weight 1484.85 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2,4,4,6,6-Hexakis(hexadecyl)-1,3,5,2,4,6-trioxatrisilinane is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1484.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
