1,3,5,7-Tetravinyltetramethylcyclotetrasiloxane CAS 25898-37-7 chemical structure

Description

CATO supplies 1,3,5,7-Tetravinyltetramethylcyclotetrasiloxane (CAS 25898-37-7), a certified reference material (molecular formula C8H10Cl2Si, MW 205.16 g/mol) for analytical method development and quality control.

1,3,5,7-Tetravinyltetramethylcyclotetrasiloxane (C8H10Cl2Si) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 1,3,5,7-Tetravinyltetramethylcyclotetrasiloxane 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.
