| | 2-Isobutylthiazole Usage And Synthesis |
| 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. | | Uses | 2-Isobutylthiazole is used as a food flavoring. | | Preparation | By cyclization of aliphatic amides with α,β-dibromo ether. | | Definition | ChEBI: A 1,3-thiazole in which the hydrogen at position 2 has been replaced by an isobutyl group.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. | | Aroma threshold values | Detection: 3.5 ppb |
