2-N-PROPYLPYRIDINE Usage And Synthesis
| Chemical Properties | Liquid. Boiling point 170°C (169-171°C), relative density 0.912, refractive index 1.4925, flash point 56°C. |
| Occurrence | Reportedly present in beef (boiled, cooked), oat groats (toasted) and oatmeal (cooked). |
| Uses | Traces of 2-Propylpyridine may introduce natural, green-tobacco-like, herbaceous notes in a Fougere or Chypre, particularly in conjunction with Oakmoss, Lavender, Phenylacetates, etc. |
| Production Methods | 2-Propylpyridine is produced: 1) by Wolff-Kishner reduction of Propionyl pyridine. This process yields exclusively the alpha-isomer (if intermediate alpha was used). 2) from Pyridine and n-Propylbromide. This process yields a mixture of alpha- and gamma-isomers. |
| Definition | ChEBI: 2-Propylpyridine is a member of pyridines. |
| Aroma threshold values | Detection at 0.011 mg/m3 in air. |
