75782-22-8 Usage
General Description
2-Propanone,1-(2-pyrimidinyl)-, also known as [[2-Acetylpyridine]], is a yellow crystalline compound with a molecular formula C8H7N2O. It is commonly used as a flavoring agent in the food industry and as a fragrance in the cosmetic industry, due to its pleasant and fruity odor. This chemical is also used in the synthesis of pharmaceuticals and agrochemicals. It is important to handle this compound with care, as it can be harmful if ingested or inhaled, and can cause irritation to the skin and eyes. Additionally, exposure to high concentrations of this chemical may cause dizziness and headaches.
Check Digit Verification of cas no
The CAS Registry Mumber 75782-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,8 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75782-22:
(7*7)+(6*5)+(5*7)+(4*8)+(3*2)+(2*2)+(1*2)=158
158 % 10 = 8
So 75782-22-8 is a valid CAS Registry Number.

SRN1 Mechanism in Heteroaromatic Nucleophilic Substitution. Reactions Involving Halogenated Pyrimidines, Pyridazines, and Pyrazines
Carver, David R.,Komin, Andrew P.,Hubbard, James S.,Wolfe, James S.
, p. 294 - 299 (2007/10/02)
Reactions of 2-chloropyrimidine (1), 4-chloro-2,6-dimethoxypyrimidine (7), 3-chloro-6-methoxypyridazine (9), and 2-chloropyrazine (14) with a representative series of ketone enolates in liquid ammonia exhibited characteristics consistent with a radical-chain (SRN1) mechanism for substituton.Diazines 1 and 9 showed an unexpected sensitivity to enolate ion structure, with 1 reacting best with tertiary enolates and 9 undergoing substitution most satisfactorily with primary enolates.The order of SRN1 reactivity among the various substrates was found to be 14 > 9 > 7 =ca. 1.Thus 1 and 7 required photostimulation at 35o nm for satisfactory displacemement of chloride, 9 underwent some substitution without illumination, and 14 reacted smoothly in the dark.
