General description

Potassium L-tartrate is found naturally in grapes. Its removal is necessary during wine making as it can precipitate, which is undesirable.[1]

Application

Potassium L-tartrate monobasic may be used as a reductant during the synthesis of noble metal nanoparticles in the presence of linear polymers as protective agents.[2]
