Chemical Structure

(3-Mercaptopropyl)trimethoxysilane CAS 4420-74-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 196.34 g/mol gives (3-Mercaptopropyl)trimethoxysilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Mercaptopropyl)trimethoxysilane (CAS 4420-74-0) is a high-purity analytical reference standard with the molecular formula C6H16O3SSi and a molecular weight of 196.34 g/mol.

(3-Mercaptopropyl)trimethoxysilane (C6H16O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

As a certified reference material (CRM), (3-Mercaptopropyl)trimethoxysilane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
