Chemical Structure

Octadecylsilane CAS 18623-11-5 chemical structure

Description

The occurrence of Octadecylsilane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Octadecylsilane (CAS 18623-11-5) is a high-purity analytical reference standard with the molecular formula C18H40Si and a molecular weight of 284.60 g/mol.

Structurally, Octadecylsilane (C18H40Si) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 284.60 g/mol, it falls into the medium-molecular-weight range. 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 Octadecylsilane 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.
