What is 2-Isobutylthiazole?
Description
2-Isobutylthiazole has an odor of tomato leaves. Synthesized via cyclization of aliphatic amides with a,p-dibromo ether.
Chemical properties
Colorless to light yellow liqui
Chemical properties
2-Isobutylthiazole has a tomato leaf odor.
Occurrence
Reportedly identified as the odorous component of tomatoes and in processed tomatoes.
Definition
ChEBI: A 1,3-thiazole in which the hydrogen at position 2 has been replaced by an isobutyl group. A food flavour component with a green note that adds the characteristics of ripe tomatoes. Used in blackcurrent, papaya, melon, raspberry, and roast beef flavours, i also enhances the flavour of fresh lime.
Preparation
By cyclization of aliphatic amides with α,β-dibromo ether.
Aroma threshold values
Detection: 3.5 ppb
