Potassium Sodium Tartrate, Tetrahydrate,

Piezoelectric compound for protein crystallography & Fehling's solution ingredient. Potassium Sodium Tartrate, Tetrahydrate, Granular, USP grade, is also known as Seignette's salt or Rochelle salt. It is a clear-white granular crystal that exhibits piezoelectricity. This unique property makes it an essential compound in protein crystallography, where it serves as a common precipitant. It is also an ingredient in Fehling's solution, a chemical reagent formerly used in the determination of reducing sugars in solutions. Additionally, it is a component of the Biuret reagent, which is used to measure protein concentration. Potassium Sodium Tartrate, Tetrahydrate, Granular, USP grade, has a minimum assay of 99.0%, maximum of 102.0%, and a typical value of 99.7%. It contains less than 0.001% heavy metals and has a specific gravity of 1.79. The product has a formula weight of 283.22 and a melting point of 75ºC. This product is suitable for manufacturing, processing, repackaging, or research purposes only and should be handled by experienced personnel.
