Chemical Structure
Description
The molecular framework of 1,3-Bis(2-(7-oxabicyclo[4.1.0]heptan-3-yl)ethyl)-1,1,3,3-tetramethyldisiloxane (C20H38O3Si2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
1,3-Bis(2-(7-oxabicyclo[4.1.0]heptan-3-yl)ethyl)-1,1,3,3-tetramethyldisiloxane (CAS 18724-32-8) is a high-purity analytical reference standard with the molecular formula C20H38O3Si2 and a molecular weight of 382.68 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
