| Application: | Hydrazine sulfate salt can be used as a reactant to synthesize sulfonated polyoxadiazoles in the presence of non-sulfonated diacids in polyphosphoric acid. It is also used as a modifier in the functionalization of microcrystalline cellulose, which is used as an adsorbent for the removal of dyes from water. |
