15986-93-3 Usage
General Description
2-ethyl-5,6-dihydro-3-methylpyrazine is a chemical compound with a molecular formula C8H14N2. It is a colorless liquid with a strong, musty odor that is commonly used as a flavoring agent in the food industry. It is naturally present in certain foods such as coffee, cocoa, and roasted peanuts, and is responsible for their characteristic aroma. It is also used as a fragrance in perfumes and cosmetic products. Additionally, 2-ethyl-5,6-dihydro-3-methylpyrazine has been studied for its potential applications in the pharmaceutical and agricultural industries. However, it is important to handle this compound with care as it can be irritating to the skin, eyes, and respiratory system if inhaled or ingested in high concentrations.
Check Digit Verification of cas no
The CAS Registry Mumber 15986-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,8 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15986-93:
(7*1)+(6*5)+(5*9)+(4*8)+(3*6)+(2*9)+(1*3)=153
153 % 10 = 3
So 15986-93-3 is a valid CAS Registry Number.

A green synthesis of quinoxalines and 2,3-dihydropyrazines
Delpivo, Camilla,Micheletti, Gabriele,Boga, Carla
, p. 1546 - 1552 (2013/06/27)
Quinoxaline and dihydropyrazine derivatives were obtained in high yields by simple addition of 1,2-diamines and 1,2-dicarbonyl compounds in water. In some cases, the products spontaneously precipitated from the reaction mixture, making it possible to recover and reuse the mother liquor for further condensations. The very mild reaction conditions, the high yields of the products, and the absence of any catalyst make this methodology an efficient and green route to quinoxalines and dihydropyrazines.
