Chemical Structure

Triethoxysilylundecanal CAS 116047-42-8 chemical structure

Description

The occurrence of Triethoxysilylundecanal is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Triethoxysilylundecanal (CAS 116047-42-8), molecular formula C17H36O4Si and molecular weight 332.55 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Triethoxysilylundecanal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
