应用
Reagent for determination of C-terminal amino acidsHydrazine sulfate is used in analytical chemistry for the gravimetric estimation of nickel, cobalt and cadmium. It is also used in the refining of rare metals as well as in the separation of polonium from tellurium. It finds application in the synthesis of chemical intermediate and organic compounds. Further, it acts as an antioxidant in soldering flux for light metals and as a precursor to hydrazine.
