Chemical Structure

Dioctadecylbis(3-phenylpropyl)silane CAS 18822-34-9 chemical structure

Description

Structurally, Dioctadecylbis(3-phenylpropyl)silane (C54H96Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 773.43 g/mol, it falls into the high-molecular-weight range. 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).

CATO supplies Dioctadecylbis(3-phenylpropyl)silane (CAS 18822-34-9), a certified reference material (molecular formula C54H96Si, MW 773.43 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
