Uses

2-Pentylfuran-d11 is the labeled analogue of 2-Pentylfuran (P284953), a volatile compound that is detected in meat smoke aerosol, rice aroma and tomato paste volatiles.

Definition

ChEBI: 2-pentylfuran is a member of the class of furans that is furan in which the hydrogen at position 2 is replaced by a pentyl group. It is found in many heat-processed foods and drinks. It has a role as an Aspergillus metabolite, a human urinary metabolite, a volatile oil component, an insect repellent, a flavouring agent, a plant growth stimulator and a bacterial metabolite.

Preparation

From 2-furyl-1-pentene by catalytic reduction with Raney-Ni.

Aroma threshold values

Detection: 6 ppb

Taste threshold values

Taste characteristics at 15 ppm: green, waxy with a cooked caramellic nuance.

General Description

2-Pentylfuran is produced by Aspergillus fumigatus in vitro, when cultured on blood agar, nutrient agar and other medically important fungi including?Aspergillus flavus, Aspergillus niger, Scedosporum apiospermum?and?Fusarium?species.

Safety Profile

Moderately toxic by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors.
