Chemical Structure

Hexamethyldisiloxane CAS 107-46-0 chemical structure

Description

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.

Hexamethyldisiloxane (CAS 107-46-0), molecular formula C6H18OSi2 and molecular weight 162.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H18OSi2, Hexamethyldisiloxane contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 162.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

As a certified reference material (CRM), Hexamethyldisiloxane 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.
