Chemical Structure

Eicosamethylcyclodecasiloxane CAS 18772-36-6 chemical structure

Description

The molecular framework of Eicosamethylcyclodecasiloxane (C20H60O10Si10) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

CATO supplies Eicosamethylcyclodecasiloxane (CAS 18772-36-6), a certified reference material (molecular formula C20H60O10Si10, MW 741.54 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Eicosamethylcyclodecasiloxane 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.
