Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 1,1,3,3-Tetramethyl-1-(2-(trimethoxysilyl)ethyl)disiloxane (CAS 137407-65-9), a certified reference material (molecular formula C9H26O4Si3, MW 282.56 g/mol) for analytical method development and quality control.
The molecular framework of 1,1,3,3-Tetramethyl-1-(2-(trimethoxysilyl)ethyl)disiloxane (C9H26O4Si3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
