5-Nitroisoquinoline (cas: 607-32-9) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. The discovery of chloroquine, the most well-known drug containing this stent, has helped bring about decades of malaria control and treatment.Safety of 5-Nitroisoquinoline

Solid supported Pd(0): an efficient recyclable heterogeneous catalyst for chemoselective reduction of nitroarenes was written by Shil, Arun K.;Sharma, Dharminder;Guha, Nitul Ranjan;Das, Pralay. And the article was included in Tetrahedron Letters in 2012.Safety of 5-Nitroisoquinoline This article mentions the following:

Solid supported palladium(0) (SS-Pd) catalyzed highly chemoselective reduction of nitroarenes to the corresponding anilines was accomplished under a milder reaction condition. This catalyst showed high compatibility with various reducing agents (NaBH4, Et3SiH, and NH2NH2·H2O) and a large number of reducible functional groups such as sulfonamide, amides, carboxylic acid, ester, alc., halide, hetero cycle, nitrile, alkene, carbonyl, O-benzyl, and N-benzyl were tolerated. Most of the reactions were clean and high yielding. The SS-Pd catalyst could be recycled up to seven runs without significant loss of activity. In the experiment, the researchers used many compounds, for example, 5-Nitroisoquinoline (cas: 607-32-9Safety of 5-Nitroisoquinoline).
