Chemical Structure
Description
The occurrence of Octakis(tetramethylammonium)-t8-silsesquioxane is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Octakis(tetramethylammonium)-t8-silsesquioxane (CAS 56982-91-3) is a high-purity analytical reference standard with the molecular formula O20Si8C4H12N and a molecular weight of 618.81 g/mol.
Owing to a carbohydrate-derived structure, an amide group, Octakis(tetramethylammonium)-t8-silsesquioxane is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 618.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
