Sigma Aldrich Fine Chemicals Biosciences Toluene-d8 99 atom D10G
Toluene-d8 is a deuterated derivative of toluene. Pyrolytic decomposition of dilute mixtures (concentration range 5-20ppm) of toluene-d8 in argon behind shock waves has been reported to afford various concentrations of hydrogen and deuterium atoms. This pyrolytic reaction was investigated by resonance absorption spectroscopy. It participates as solvent in the time-course 1H-NMR (Proton Nuclear Magnetic Resonance) spectral evaluation of (E)-dimethyl 2-(ferrocenylethynyl)-3-(4-nitrophenylethynyl)fumarate on irradiation with light at 546 and 578nm.
