5-Nitroindazole Usage And Synthesis

Chemical Properties

light yellow crystal

Uses

5-Nitroindazole inhibits citrulline formation by Ca2+-calmodulin (CaM)-dependent nitric oxide synthase from bovine brain. Nitration of 5-nitroindazole with nitric acid and acetic anhydride yields 3,5-dintroindazole and 2,5-dinitroindazole.
