2-Pentylpyridine Usage And Synthesis

Chemical Properties

2-Pentylpyridine has a tallowy-like odor.

Occurrence

Reported as occurring in shallow-fried beef and as a steam-volatile component in roasted Spanish peanut. Also reported found in bell pepper, black sesame seeds, roast turkey, fried chicken, fried beef, cooked beef, mutton, lamb fat, roasted filberts, toasted oats and coriander seed.

Definition

ChEBI: 2-Pentylpyridine is a member of pyridines.

Preparation

By alkylation of 2-pycollyl lithium; by hydrogenation of 2-pentenyl pyridine.

Aroma threshold values

Detection: 0.6 ppb. Aroma characteristics at 0.1%: strong fresh green vegetative, peppery, mushroom, herbal and oily.

Taste threshold values

Taste characteristics at 1 ppm: green pepper vegetative, mushroom-like, musty, oily, meaty and MSG-like.

Purification Methods

Dry it with NaOH for several days, then distil it from CaO under reduced pressure, taking the middle fraction and redistilling it. The picrate has m 72-72.8o (from EtOH). [Beilstein 20 III/IV 2835.] 3-n-Pentylpyridine, purified as the 2-isomer, has b 110-112o/20mm, 224-226o/748mm, and the picrate has m 79.5-80o(from EtOH). [Beilstein 20 III/IV 2835.]
