Chemical Structure

Trimethyl(propoxy)silane CAS 1825-63-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 343.46 g/mol gives Trimethyl(propoxy)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Trimethyl(propoxy)silane (CAS 1825-63-4), molecular formula C21H29NO3 and molecular weight 343.46 g/mol, is a CATO reference standard with documented purity and traceability.

Trimethyl(propoxy)silane (C21H29NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Trimethyl(propoxy)silane 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.
