Chemical Structure

1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane CAS 69304-37-6 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.

1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane (CAS 69304-37-6), molecular formula C12H28Cl2OSi2 and molecular weight 315.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane (C12H28Cl2OSi2) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. 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.

CATO manufactures 1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane 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.
