Chemical Structure

1,2,2,3,3,4,4,5,5,6,6-Undecaphenylhexasilinane CAS 500297-50-7 chemical structure

Description

1,2,2,3,3,4,4,5,5,6,6-Undecaphenylhexasilinane (CAS 500297-50-7), molecular formula C66H56Si6 and molecular weight 1017.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2,2,3,3,4,4,5,5,6,6-Undecaphenylhexasilinane (C66H56Si6) 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.

CATO manufactures 1,2,2,3,3,4,4,5,5,6,6-Undecaphenylhexasilinane 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.
