2-N-PROPYLPYRIDINE Chemical Properties,Usage,Production

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.
