Chemical Structure

1,1-Dimethoxy-3-(trimethylsiloxy)-1,3-butadiene CAS 61539-61-5 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 1,1-Dimethoxy-3-(trimethylsiloxy)-1,3-butadiene.

1,1-Dimethoxy-3-(trimethylsiloxy)-1,3-butadiene (CAS 61539-61-5) is a high-purity analytical reference standard with the molecular formula C9H18O3Si and a molecular weight of 202.32 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,1-Dimethoxy-3-(trimethylsiloxy)-1,3-butadiene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
