Chemical Structure

(Carboxyalkyl)TerminatedPolyDimethylsiloxane CAS 158465-59-9 chemical structure

Description

The molecular framework of (Carboxyalkyl)TerminatedPolyDimethylsiloxane (C14H32O6Si3) 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.

(Carboxyalkyl)TerminatedPolyDimethylsiloxane (CAS 158465-59-9) is a high-purity analytical reference standard with the molecular formula C14H32O6Si3 and a molecular weight of 380.66 g/mol.

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 (Carboxyalkyl)TerminatedPolyDimethylsiloxane 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.
