General description
Potassium disulfite (Potassium metabisulfite, PMB) is an inorganic salt with antimicrobial properties. It is a sulfiting agent that prevents browning of foods. Its genotoxic and cytotoxic effect has been assessed. PMB undergoes hydrolysis to form potassium bisulfite.
Application
Potassium disulfite has been used in a protocol for the modification of the polydimethylsiloxane (PDMS) polymer surfaces.
It may be used in the following processes:
It may be used in the following processes:
- Chemical etching of poly(vinylidene fluoride) in β-phase (β-PVDF) irradiated films.
- Decolorization during the synthesis of 2-iodopyrimidine derivatives.
- Palladium-catalyzed aminosulfonylation of aryl halides.

A high-yield synthesis was developed for the preparation of 2,2'-bipyrimidine (1) using the Ullmann coupling of 2-iodopyrimidine. The new procedure was also used for the preparation of 4,4',6,6'-tetramethyl-2,2'-bipyrimidine (2) and 5,5'-dibromo-2,2'-bipyrimidine (3).
