Chemical Structure

2,2,3,3,8,8,9,9-Octamethyl-4,7-dioxa-3,8-disiladecane CAS 66548-22-9 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 2,2,3,3,8,8,9,9-Octamethyl-4,7-dioxa-3,8-disiladecane.

CATO supplies 2,2,3,3,8,8,9,9-Octamethyl-4,7-dioxa-3,8-disiladecane (CAS 66548-22-9), a certified reference material (molecular formula C14H34O2Si2, MW 290.59 g/mol) for analytical method development and quality control.

Structurally, 2,2,3,3,8,8,9,9-Octamethyl-4,7-dioxa-3,8-disiladecane (C14H34O2Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 290.59 g/mol, it falls into the medium-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.

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.

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.
