Chemical Structure

1,1,1,5,5,5-Hexamethyl-3-phenyl-3-(trimethylsilyloxy)trisiloxane CAS 2116-84-9 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.

CATO supplies 1,1,1,5,5,5-Hexamethyl-3-phenyl-3-(trimethylsilyloxy)trisiloxane (CAS 2116-84-9), a certified reference material (molecular formula C15H32O3Si4, MW 372.75 g/mol) for analytical method development and quality control.

Structurally, 1,1,1,5,5,5-Hexamethyl-3-phenyl-3-(trimethylsilyloxy)trisiloxane (C15H32O3Si4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 372.75 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1,1,1,5,5,5-Hexamethyl-3-phenyl-3-(trimethylsilyloxy)trisiloxane 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.
