Diphenyldi-m-tolylsilane CAS 18849-26-8 chemical structure

Description

CATO manufactures Diphenyldi-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.

Diphenyldi-m-tolylsilane (CAS 18849-26-8), molecular formula C26H24Si and molecular weight 364.55 g/mol, is a CATO reference standard with documented purity and traceability.

Diphenyldi-m-tolylsilane (C26H24Si) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
