2-Acetylthiazole Chemical Properties,Uses,Production
Chemical Properties
2-Acetylthiazole is a colorless to pale yellow liquid with green onion, herbal, grassy, hazelnuts, roasted meat, caramel, corn, and butter odor. Natural products are found in beef broth. Slightly soluble with water, soluble in most organic solvents. It is used in foods as antioxidant, as appearance control agent, and as flavoring ingredient.
Occurrence
2-Acetylthiazole is naturally found in raw asparagus, cooked asparagus, kohlrabi, cooked or boiled potatoes, turkey (roasted), raw chicken, boiled and cooked beef, grilled and roasted beef, pork liver, beer, Finnish whiskey, heated beans, other varieties of mushroom, rice bran, maize, and other natural sources.
Uses
2-Acetylthiazole can be used as a flavoring agent in food industries. It may be used as a food additive in the preparation of ′fragrant′ rice. It also was used in the preparation of triazolothiazoles, chiral alcohols and in aldol condensation reactions.
Definition
ChEBI: 2-Acetylthiazole is an aromatic ketone.
Preparation
2-Acetylthiazole is formed by oxidation of the corresponding carbinol using dichromate.

General Description
2-Acetylthiazole is a volatile flavoring substance generally formed by the Maillard reaction between an amino acid and carbonyl compounds. It is reported to occur in canned sweet corn products, cooked pine mushroom, cooked asparagus and roasted beef.
Purification Methods
Check NMR spectrum; if it is not too bad, distil it through an efficient column in a vacuum. The oxime sublimes at 140-145o, m 159o, and when crystallised from H2O has m 163-165.5o.
