Application

Sodium bisulfite (NaHSO3) has been used as a reagent to compose the immunoprecipitation (IP) buffer to chemically modify DNA and to synthesize arsenolipids (AsL).
It can also be used as a reagent during the synthesis of 5,6-dihydrouracil-6-sulfonate.

General description

The aqueous solutions of sodium bisulfite are acidic in nature. Degradation of sodium bisulfite with acid forms sulfur dioxide gas.
