Potassium Sodium Tartrate Tetrahydrate, widely known by its historical name Rochelle Salt, is a chemical compound that has captivated scientists and industry professionals for centuries. Its unique crystalline structure and chemical behavior lend it to a surprisingly broad array of applications, from early piezoelectric research to its current uses in pharmaceuticals, food, and various chemical processes. Understanding the nuances of this compound and knowing where to source it reliably are key for any business that utilizes it.

The chemical identity of Potassium Sodium Tartrate Tetrahydrate is defined by its CAS number, 6381-59-5. It is a double salt formed from potassium and sodium tartrates. Its physical appearance is typically described as colorless, translucent crystals or a white crystalline powder, often with a faint odor. The compound is known for its deliquescent nature, meaning it can absorb moisture from the air, a factor that influences its storage and handling. For instance, its solubility in water is substantial, with higher concentrations at warmer temperatures.

Historically, Rochelle Salt gained prominence for its piezoelectric properties, being one of the first materials discovered to exhibit this phenomenon. This led to its use in early transducers for microphones and phonograph cartridges. While newer materials have largely replaced it in these specific applications, its legacy in materials science is significant. Modern research continues to explore its potential, particularly in composite materials for sensing and energy absorption.

In contemporary applications, its utility remains high. In the pharmaceutical industry, it's used in diagnostic reagents and as a mild laxative. The food industry utilizes it as a component in baking powders and as a stabilizer. Industrially, it serves as a complexing agent in electroplating and a desulfurizer in gas treatment.
