Chemical Structure

Didodecyldi-m-tolylsilane CAS 18856-18-3 chemical structure

Description

The molecular framework of Didodecyldi-m-tolylsilane (C38H64Si) is characterized by a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Didodecyldi-m-tolylsilane (CAS 18856-18-3), a certified reference material (molecular formula C38H64Si, MW 549.00 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.

CATO manufactures Didodecyldi-m-tolylsilane 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.
