2-Acetylthiazole Usage And Synthesis
Chemical Properties | A colorless liquid with green onion, herbal, grassy odor. It is used as flavor enhancer and flavoring agent |
Preparation | By oxidation of the corresponding carbinol using dichromate |
Aroma threshold values | Detection at 4 ppb |
Taste threshold values | Taste characteristics at 30 ppm: corn chip with slightly musty background |
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. [Erlenmeyer et al. Helv Chim Acta 31 1142 1948, Waisvisz et al. J Am Chem Soc 79 4524 1957, Menasseé et al.
