General Description

2-Methyl-3-isopropylpyrazine is a chemical compound with a molecular formula C8H12N2. It is a colorless liquid at room temperature and is commonly used as a flavoring agent in the food and beverage industry due to its strong nutty and roasted aroma. It is also found naturally in foods such as roasted coffee and cocoa. Additionally, it has been studied for its potential use in insect repellents and pheromones due to its strong and distinct odor. As a result of its unique aroma, 2-Methyl-3-isopropylpyrazine is commonly used in products such as perfumes and other cosmetic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 15986-81-9 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, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15986-81:
(7*1)+(6*5)+(5*9)+(4*8)+(3*6)+(2*8)+(1*1)=149
149 % 10 = 9
So 15986-81-9 is a valid CAS Registry Number.

The Wolff-Kishner Reduction of 2-Acetonyl Pyrazines and Pyridines. A Novel Rearrangement

Paine III, John B.

, p. 1463 - 1465 (2007/10/02)

Wolff-Kishner reduction of 1-(6-methylpyrazin-2-yl)-2-propanone leads to the formation of 2-isopropyl-6-methylpyrazine (2a), in addition to the expected 6-methyl-2-n-propylpyrazine.The by-product 2a is suggested to arise via a spirocyclopropylidene aza-anion, which serves as a conduit between the initial less-stable secondary 1-(2-pyrazinyl)-2-propyl carbanion and the more stable primary 2-(2-pyrazinyl)-1-propyl carbanion.Similar results were observed for the 1-(3-methylpyrazin-2-yl) and 1-(6-methylpyridin-2-yl)-2-propanones.The extent of by-product formation diminished in the pyridine ring system.Electrophilic activation of the ring appears essential since the benzene ring analog phenylacetone gave no detectable cumene under identical reaction conditions.
