2,2,7,7-tetramethyl-4-((trimethylsilyl)oxy)-3,6-dioxa-2,7-disilaoct-4-ene 69097-20-7 tris(trimethylsilyloxy)ethylene CAS 69097-20-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,7,7-tetramethyl-4-((trimethylsilyl)oxy)-3,6-dioxa-2,7-disilaoct-4-ene 69097-20-7 tris(trimethylsilyloxy)ethylene.

CATO supplies 2,2,7,7-tetramethyl-4-((trimethylsilyl)oxy)-3,6-dioxa-2,7-disilaoct-4-ene 69097-20-7 tris(trimethylsilyloxy)ethylene (CAS 69097-20-7), a certified reference material (molecular formula C11H28O3Si3, MW 292.59 g/mol) for analytical method development and quality control.

The molecular framework of 2,2,7,7-tetramethyl-4-((trimethylsilyl)oxy)-3,6-dioxa-2,7-disilaoct-4-ene 69097-20-7 tris(trimethylsilyloxy)ethylene (C11H28O3Si3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2,2,7,7-tetramethyl-4-((trimethylsilyl)oxy)-3,6-dioxa-2,7-disilaoct-4-ene 69097-20-7 tris(trimethylsilyloxy)ethylene 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.
