Chemical Structure

1,1,1,6,6,6-Hexamethyl-2,2,3,3,4,4,5,5-octaphenylhexasilane CAS 89634-96-8 chemical structure

Description

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

1,1,1,6,6,6-Hexamethyl-2,2,3,3,4,4,5,5-octaphenylhexasilane (CAS 89634-96-8), molecular formula C54H58Si6 and molecular weight 875.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,1,6,6,6-Hexamethyl-2,2,3,3,4,4,5,5-octaphenylhexasilane (C54H58Si6) 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).

As a certified reference material (CRM), 1,1,1,6,6,6-Hexamethyl-2,2,3,3,4,4,5,5-octaphenylhexasilane 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.
