Chemical Structure
Description
CATO supplies Tris(2-cyclohexylethyl)(phenyl)silane (CAS 18758-76-4), a certified reference material (molecular formula C30H50Si, MW 438.80 g/mol) for analytical method development and quality control.
The molecular framework of Tris(2-cyclohexylethyl)(phenyl)silane (C30H50Si) is characterized by an aromatic ring system. 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).
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 manufactures Tris(2-cyclohexylethyl)(phenyl)silane 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.
