Chemical Structure

Ethoxydiphenyl(vinyl)silane CAS 17933-85-6 chemical structure

Description

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.

CATO supplies Ethoxydiphenyl(vinyl)silane (CAS 17933-85-6), a certified reference material (molecular formula C16H18OSi, MW 254.40 g/mol) for analytical method development and quality control.

Structurally, Ethoxydiphenyl(vinyl)silane (C16H18OSi) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 254.40 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.

As a certified reference material (CRM), Ethoxydiphenyl(vinyl)silane 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.
