Description

  • General description: Potassium disulfite (Potassium metabisulfite, PMB) is an inorganic salt with antimicrobial properties.[1] It is a sulfiting agent that prevents browning of foods.[2] Its genotoxic and cytotoxic effect has been assessed.[1] PMB undergoes hydrolysis to form potassium bisulfite.[3]
  • Application: Potassium disulfite has been used in a protocol for the modification of the polydimethylsiloxane (PDMS) polymer surfaces.[4]It may be used in the following processes:Chemical etching of poly(vinylidene fluoride) in β-phase (β-PVDF) irradiated films.[5]Decolorization during the synthesis of 2-iodopyrimidine derivatives.[6]Palladium-catalyzed aminosulfonylation of aryl halides.[7]
