5-Bromo-2-phenoxypyrimidine (cas: 257280-25-4) belongs to pyrimidine derivatives. Pyrimidines are isomeric with two other forms of diazines: pyridazine, with the nitrogen atoms in the 1 and 2 positions; and pyrazine, with the nitrogen atoms in the 1 and 4 positions. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.COA of Formula: C10H7BrN2O

Heteroaryl ethers by oxidative palladium catalysis of pyridotriazol-1-yloxy pyrimidines with arylboronic acids was written by Bardhan, Sujata;Wacharasindhu, Sumrit;Wan, Zhao-Kui;Mansour, Tarek S.. And the article was included in Organic Letters in 2009.COA of Formula: C10H7BrN2O This article mentions the following:

The oxidative palladium-catalyzed cross-coupling of pyrimidines containing pyridotriazol-1-yloxy (OPt) as either a urea or an amide functional group with arylboronic acids in the presence of Cs2CO3 in DME containing 0.6-1.0% H2O is described for the preparation of heteroaryl ethers. The bromo substitution in the case of 3-(5-bromo-pyrimidin-2-yloxy)-3H-[1,2,3]triazolo[4,5-b]pyridine could serve as a handle for further elaborations such as Suzuki coupling for attaching varied aryl groups. In the experiment, the researchers used many compounds, for example, 5-Bromo-2-phenoxypyrimidine (cas: 257280-25-4COA of Formula: C10H7BrN2O).
