Beschreibung

Allgemeine Beschreibung

Toluene-d₈ is a deuterated NMR solvent. It is an anhydrous solvent, which minimizes any interference from water peaks. It is useful in performing critical air- and moisture-sensitive NMR analysis. Its spin–lattice relaxation time (T ₁), viscosity and density have been measured over -35 to 200°C range. The temperature dependent chemical shifts in the proton NMR spectra of α,β-unsaturated ketones in toluene-d₈ has been studied.
