Synthesis
In 1993 Suzuki and co-workers reported the nitration of pyridine with nitrogen dioxide and ozone in dichloromethane at room temperature. They obtained a 3.5 % yield of 3-nitropyridine and 1.2 % of 3,5-dinitropyridine. 3-Nitropyridines can also be synthesized by oxidation of 3-aminopyridine with hydrogen peroxide in fuming sulphuric acid in 45% yield. Nitration of 2,6-dichloropyridine with nitronium tetrafluoroborate gave a 11% yield of 3-nitropyridine after dehalogenation. 3-nitropyridine has also been prepared from 2- chloro-3-nitropyridine.
Check Digit Verification of cas no
The CAS Registry Mumber 2530-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,3 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2530-26:
(6*2)+(5*5)+(4*3)+(3*0)+(2*2)+(1*6)=59
59 % 10 = 9
So 2530-26-9 is a valid CAS Registry Number.

Exploration of relative chemoselectivity in the hydrodechlorination of 2-chloropyridines
Kinarivala, Nihar,Trippier, Paul C.
supporting information, p. 5386 - 5389 (2015/01/16)
The chemoselectivity of hydrodechlorination in 2-chloropyridine derivatives possessing reduction-sensitive functionalities is examined. The reaction conditions employed tolerate a variety of functionalities illustrating highly chemoselective hydrodechlorination in the presence of nitrile, allyl, terminal olefin, and nitroamine functionalities in excellent yield. Chemoselective deprotection of carboxybenzyl ethers is illustrated in moderate yield.
Efficient synthesis of nebularine and vidarabine via dehydrazination of (hetero)aromatics catalyzed by CuSO4 in water
Xia, Ran,Xie, Ming-Sheng,Niu, Hong-Ying,Qu, Gui-Rong,Guo, Hai-Ming
, p. 1077 - 1081 (2014/03/21)
A simple dehydrazination reaction has been achieved in the presence of a catalytic amount of CuSO4 for the first time. With CuSO4 (2 mol%) as a catalyst and water as a solvent, the dehydrazination products were obtained in good yields (66-95%). Moreover, the drugs nebularine and vidarabine were afforded successfully, and vidarabine could be produced on a 0.923 kg scale, which shows good potential for industrial applications.
