2-Pyridineacetic acid, a,a-difluoro-, also known as difludina, is a chemical compound with the molecular formula C7H6F2NO2. It is a derivative of 2-pyridineacetic acid and contains two fluorine atoms attached to the alpha carbon. 2-Pyridineacetic acid, a,a-difluoro- is used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It has also been studied for its potential use as a building block in the development of new drugs. Additionally, it has shown to have antimicrobial and antifungal properties, making it a potential candidate for use in various medical and agricultural applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1039621-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,9,6,2 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1039621-73:
(9*1)+(8*0)+(7*3)+(6*9)+(5*6)+(4*2)+(3*1)+(2*7)+(1*3)=142
142 % 10 = 2
So 1039621-73-2 is a valid CAS Registry Number.

Synthesis and some transformations of all three isomers of α,α-difluoropyridinylacetonitrile

Shavrina, Oksana M.,Bezdudny, Andrii V.,Rassukana, Yuliya V.

, (2021/04/19)

An effective preparative approach to fluorinated pyridinylacetonitriles, based on electrophilic fluorination of pyridinylacetonitriles, was developed. Their synthetic potential for obtaining new fluorine-containing building blocks and heterocyclic systems was disclosed.

Controlling the cleavage of carbon-carbon bonds to generate α,α-difluorobenzyl carbanions for the construction of difluoromethylbenzenes

Khatri, Hari R.,Han, Changho,Luong, Erica,Pan, Xiaoliang,Adam, Amna T.,Alshammari, Maali D.,Shao, Yihan,Colby, David A.

, p. 11665 - 11675 (2019/10/02)

Controlling the cleavage of carbon-carbon bonds during a chemical reaction is a substantial challenge; however, synthetic methods that accomplish this objective produce valuable and often unexplored reactivity. We have designed a mild process to generate α,α-difluorobenzyl carbanions in the presence of potassium carbonate by exploiting the cleavage of C-C bonds during the release of trifluoroacetate. The initiating reagent is potassium carbonate, which represents an improvement over existing protocols that require a strong base. Fragmentation studies across substituted arenes and heteroarenes were conducted along with computational analyses to elucidate reactivity trends. Furthermore, the mildly generated α,α-difluorobenzyl carbanions from electron-deficient aromatics and heteroaromatic rings can react with aldehydes to create derivatives of difluoromethylbenzenes, which are valuable synthetic targets.
