Chemical Structure

(But-3-yn-2-yloxy)trimethylsilane CAS 17869-76-0 chemical structure

Description

(But-3-yn-2-yloxy)trimethylsilane (CAS 17869-76-0) is a high-purity analytical reference standard with the molecular formula C7H14OSi and a molecular weight of 142.27 g/mol.

Structurally, (But-3-yn-2-yloxy)trimethylsilane (C7H14OSi) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 142.27 g/mol, it falls into the low-molecular-weight range.

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.
