Chemical Structure

Tetradecyloxysilane CAS 18845-54-0 chemical structure

Description

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

Tetradecyloxysilane (CAS 18845-54-0), molecular formula C14H32OSi and molecular weight 244.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, Tetradecyloxysilane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.49 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.

As a certified reference material (CRM), Tetradecyloxysilane 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.
