| Hazard Information | Back Directory | [Description]
2-Isobutylthiazole has an odor of tomato leaves. Synthesized via
cyclization of aliphatic amides with a,p-dibromo ether. | [Chemical Properties]
2-Isobutylthiazole has a tomato leaf odor.
| [Chemical Properties]
Colorless to light yellow liqui | [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ChEBI: A 1,3-thiazole in which the hydrogen at position 2 has been replaced by an isobutyl group.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 |
