| General description: | Pyridine-d5 is a deuterated form of pyridine having an isotopic purity of 99.96atom%D. It is 100% isotopically enriched NMR (Nuclear Magnetic Resonance) solvent. It is widely employed for high resolution NMR studies due to its high chemical and isotopic purity. The reaction between pyridine vapor and heavy water in the presence of a palladium catalyst has been reported to afford pyridine-d5. Infrared (IR), Raman (in the range 300-4000cm-1) and high-resolution (0.06cm-1) FT-IR (Fourier transform infrared) spectral studies of pyridine-d5 have been reported. |
