1,3-Bis(3-carboxypropyl)tetramethyldisiloxane CAS 3353-68-2 chemical structure

Description

CATO manufactures 1,3-Bis(3-carboxypropyl)tetramethyldisiloxane 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.

CATO supplies 1,3-Bis(3-carboxypropyl)tetramethyldisiloxane (CAS 3353-68-2), a certified reference material (molecular formula C12H26O5Si2, MW 306.50 g/mol) for analytical method development and quality control.

1,3-Bis(3-carboxypropyl)tetramethyldisiloxane (C12H26O5Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
