Tetra-p-tolylsilane CAS 10256-83-4

Description

Compared with other compounds in its class, the molecular weight of 392.61 g/mol gives Tetra-p-tolylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tetra-p-tolylsilane (CAS 10256-83-4), molecular formula C28H28Si and molecular weight 392.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a polycyclic aromatic system, Tetra-p-tolylsilane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Tetra-p-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.
