Chemical Structure

Trihexadecyl(phenyl)silane CAS 18822-36-1 chemical structure

Description

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

Trihexadecyl(phenyl)silane (CAS 18822-36-1) is a high-purity analytical reference standard with the molecular formula C54H104Si and a molecular weight of 781.49 g/mol.

The molecular framework of Trihexadecyl(phenyl)silane (C54H104Si) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
