In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Quality Control of 2-Chloro-7-nitroquinoxaline, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 55686-94-7, name is 2-Chloro-7-nitroquinoxaline. In an article£¬Which mentioned a new discovery about 55686-94-7
Multi-gram preparation of 7-nitroquinoxalin-2-amine
Methodologies to obtain quinoxaline compounds regioselectively are rarely reported in literature, thus regioselective and multi-gram methodologies to obtain these derivatives are desirable to explore the entire potential of these scaffolds for academic and/or commercial application. A facile and multi-gram methodology is described to obtain compound 7-nitroquinoxalin-2-amine using o-phenylenediamine, a cheap and readily available reactant, as starting material in a five-step procedure in good yields and high purity without further purification such as crystallization or column chromatography.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 55686-94-7, help many people in the next few years.Quality Control of 2-Chloro-7-nitroquinoxaline
