Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , COA of Formula: C8H12N2, 13925-07-0, Name is 2-Ethyl-3,5-dimethylpyrazine, molecular formula is C8H12N2, belongs to piperidines compound.

Syntheses and Reactions of Pyrroline, Piperidine Nitroxide Phosphonates
Organophosphorus compounds occupy a significant position among the plethora of organic compounds, but a limited number of paramagnetic phosphorus compounds have been reported, including paramagnetic phosphonates. This paper describes the syntheses and further transformations of pyrroline and piperidine nitroxide phosphonates by well-established methods, such as the Pudovik, Arbuzov and Horner-Wadsworth-Emmons (HWE) reactions. The reaction of paramagnetic alpha -bromoketone produced a vinylphosphonate in the Perkow reaction. Paramagnetic alpha -hydroxyphosphonates could be subjected to oxidation, elimination and substitution reactions to produce various paramagnetic phosphonates. The synthesized paramagnetic phosphonates proved to be useful synthetic building blocks for carbon-carbon bond-forming reactions in the Horner-Wadsworth-Emmons olefination reactions. The unsaturated compounds achieved could be transformed into various substituted pyrroline nitroxides, proxyl nitroxides and paramagnetic polyaromatics. The Trolox((R)) equivalent antioxidant capacity (TEAC) of new phosphonates was also screened, and tertiary alpha -hydroxyphosphonatate nitroxides exhibited remarkable antioxidant activity.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 13925-07-0. COA of Formula: C8H12N2.
