Chemical Structure

1,5-Bis(trimethylsilyl)penta-1,4-diyn-3-one CAS 60836-10-4 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, 1,5-Bis(trimethylsilyl)penta-1,4-diyn-3-one is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1,5-Bis(trimethylsilyl)penta-1,4-diyn-3-one (CAS 60836-10-4) is a high-purity analytical reference standard with the molecular formula C11H18OSi2 and a molecular weight of 222.43 g/mol.

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.
