Chemical Structure

69667-29-4 Octakis(tetramethylammonium) pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane-1,3,5,7,9,11,13,15-octakis(yloxide) hydrate PSS hydrate-Octakis(tetramethylammonium) substituted CAS 69667-29-4 chemical structure

Description

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.

69667-29-4 Octakis(tetramethylammonium) pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane-1,3,5,7,9,11,13,15-octakis(yloxide) hydrate PSS hydrate-Octakis(tetramethylammonium) substituted (CAS 69667-29-4), molecular formula O20Si8C4H12NH2O and molecular weight 636.82 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, an amide group, 69667-29-4 Octakis(tetramethylammonium) pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane-1,3,5,7,9,11,13,15-octakis(yloxide) hydrate PSS hydrate-Octakis(tetramethylammonium) substituted is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 636.82 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.
