1,1,1,3,3,3-Hexaphenyldisiloxane CAS 1829-40-9 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.

1,1,1,3,3,3-Hexaphenyldisiloxane (CAS 1829-40-9), molecular formula C36H30OSi2 and molecular weight 534.79 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,1,3,3,3-Hexaphenyldisiloxane (C36H30OSi2) is characterized by a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 1,1,1,3,3,3-Hexaphenyldisiloxane 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.
