n-Octyltriethoxysilane CAS 2943-75-1 chemical structure

Description

n-Octyltriethoxysilane (CAS 2943-75-1) is a high-purity analytical reference standard with the molecular formula C14H32O3Si and a molecular weight of 276.49 g/mol.

n-Octyltriethoxysilane (C14H32O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures n-Octyltriethoxysilane 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.
