Chemical Structure

1,1,1,2,2,2-Hexa-p-tolyldisilane CAS 15931-53-0 chemical structure

Description

1,1,1,2,2,2-Hexa-p-tolyldisilane (CAS 15931-53-0), molecular formula C42H42Si2 and molecular weight 602.95 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,1,2,2,2-Hexa-p-tolyldisilane (C42H42Si2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1,1,1,2,2,2-Hexa-p-tolyldisilane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
