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.
Application:	Sodium bisulfite can be used as:• A reagent to synthesize aldehyde-bisulfite adducts from aromatic and aliphatic aldehydes. • A catalyst in the solvent-free etherification of aromatic/aliphatic alcohols to synthesize symmetric and unsymmetric ethers via intermolecular dehydration. • An additive in the copper-catalyzed homocoupling of ketoxime carboxylates to synthesize symmetrical pyrroles.
General description:	Sodium bisulfite is a widely used industrial chemical as a reducing agent, catalyst, and preservative in pharmaceuticals and foods due to its antioxidative and antibacterial effects.
General description:	The aqueous solutions of sodium bisulfite are acidic in nature. Degradation of sodium bisulfite with acid forms sulfur dioxide gas.
