Chemical Structure

Octamethyl trisilicate CAS 4221-95-8 chemical structure

Description

The occurrence of Octamethyl trisilicate is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Octamethyl trisilicate (CAS 4221-95-8), a certified reference material (molecular formula C8H24O10Si3, MW 364.53 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, Octamethyl trisilicate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

CATO manufactures Octamethyl trisilicate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
