| introduction | 2-bromothiazole is a thiazole derivative. Thiazole ring is an important five-membered aromatic heterocyclic ring, containing nitrogen and sulfur heteroatoms, rich in electrons, easy to form hydrogen bonds, coordination with metal ions, π-π accumulation, electrostatic and hydrophobic interaction and other non-covalent bond interactions, this structure endows thiazole compounds with many special properties, and has a wide range of potential applications in many fields. |
| Preparation | 2-bromothiazole can be used to prepare 2-acetylthiazole. 2-Acetylthiazole is a kind of edible flavor. It is naturally found in cooked beef, cooked pork liver, asparagus, potatoes, and rice. It has a fragrance similar to nuts, rice, and popcorn. The United States has approved the use (FEMA registration number is 3328), and our GB2760-1996 stipulates that it is a food spice allowed to be used. |
| Use | Used as an intermediate for making 2-acetylthiazole |
