3-Nitropyridine
CAS :3-Nitropyridine is a nitro compound that is used in the preparation of pharmaceuticals. It has been shown to have an inhibitory effect on HIV and other viruses, which may be due to its ability to react with nucleophilic groups. 3-Nitropyridine has also been shown to have an inhibitory effect on the human immunodeficiency virus (HIV) by reacting with the acidic group of the virus. This reaction prevents the virus from binding to cells and entering them. 3-Nitropyridine is also used as a solvent for organic reactions.Formule :C5H4N2O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :124.1 g/mol[Asp371] Tyrosinase(369-377), human
