Chemical Structure

1,1,3,3,5,5-Hexamethyltrisiloxane CAS 1189-93-1 chemical structure

Description

CATO supplies 1,1,3,3,5,5-Hexamethyltrisiloxane (CAS 1189-93-1), a certified reference material (molecular formula C6H20O2Si3, MW 208.48 g/mol) for analytical method development and quality control.

1,1,3,3,5,5-Hexamethyltrisiloxane (C6H20O2Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), 1,1,3,3,5,5-Hexamethyltrisiloxane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
