Descrizione

Descrizione generale

Toluene-d8 is a non polar, aromatic solvent.

Toluene-d₈ is a deuterated NMR solvent containing 0.03% (v/v) TMS (tetramethylsilane). It is useful in NMR-based research and analyses. 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.

Applicazioni

• Organic aerosol mixing observed by single-particle mass spectrometry.: The study focuses on the dynamics of organic aerosols, utilizing advanced spectrometric techniques to analyze the interaction and transformation of airborne organic compounds such as Toluene-d₈ (Robinson et al., 2013).

Azioni biochim/fisiol

Toluene-d8 is used in the determination of magnitude of magnetic interactions, hydrogen bond geometry and its association with solvent polarity. Toluene is highly biotoxic and lethal for microorganisms, therefore can be used as a sterilant.
