Chemical Structure

Diphenylmethylsilane CAS 776-76-1 chemical structure

Description

Diphenylmethylsilane (CAS 776-76-1), molecular formula C13H14Si and molecular weight 198.34 g/mol, is a CATO reference standard with documented purity and traceability.

Diphenylmethylsilane (C13H14Si) contains an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Diphenylmethylsilane 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.
