Application:
Pyrazine (CAS: 290-37-9) is a heterocyclic aromatic organic compound and can be reacted to obtain diverse pyrazine derivatives. Pyrazines are important contributors to the flavor of various roasted, toasted, or similarly heated foods. Pyrazine derivatives exhibit a wide variety of aromas in food, e.g. 2-Methoxy-3-Isopropylpyrazine produces a green pea odor. Pyrazines and pyrazine derivatives are typically used as flavor agent. Pyrazines and Pyrazine derivatives are also used as fragrances. Pyrazine has a strong pyridine-like odor. Pyrazine is employed as pharmaceutical intermediates, perfume intermediates and involved in the preparation of other chemicals. A heterocyclic aromatic compound with a six-membered ring containing four carbon atoms and two nitrogen atoms. Pyrazine is mainly used for the synthesis of various essence such as meat, chocolate, peanut and popcorn. It can also be used as an intermediate for the synthesis of antituberculosis drugs, pyrazine amide, diuretic drug, aminopiroyl guanidine and oral antidiabetic drug glipizide. A variety of pharmaceutical and pesticide intermediates such as oxazine. Used in the manufacture of resins and polymers and pharmaceuticals.
