Potassium Sodium Tartrate, commonly known as Rochelle Salt or Seignette Salt, is a fascinating chemical compound with a rich history and an impressively diverse range of applications. First synthesized by Pierre Seignette in La Rochelle, France, around 1672, this double salt of tartaric acid has become indispensable across various industries. NINGBO INNO PHARMCHEM CO.,LTD. is proud to be a leading provider of high-purity Potassium Sodium Tartrate, meeting the rigorous demands of global markets.

Chemically, Potassium Sodium Tartrate is identified by CAS No. 304-59-6, with the molecular formula C4H4KNaO6 and a molecular weight of 210.16. It typically presents as a white, odorless crystalline powder with a characteristic saline taste. This compound is highly soluble in water, forming solutions with a pH ranging from 7.0 to 8.5, highlighting its neutral to slightly alkaline nature. While stable under proper storage conditions, it exhibits efflorescent properties, meaning it tends to lose water of crystallization when exposed to air, emphasizing the importance of airtight packaging in a cool, dry environment.

The utility of Potassium Sodium Tartrate spans numerous sectors, particularly in the food and pharmaceutical industries. In food processing, it serves as an effective baking powder, contributing to leavening and texture. It is also widely used as a food additive (E337), functioning as an emulsifier, sequestrant, and pH control agent, notably in the production of pectins and meat preservatives. Medicinally, Rochelle Salt has a historical role as a mild saline laxative and is recognized as a component in certain formulations. Furthermore, its crucial role as a laboratory reagent cannot be overstated, being a key ingredient in Fehling's solution for detecting reducing sugars and in Biuret reagent for protein concentration measurements. It also acts as a common precipitant in protein crystallography, aiding in the structural analysis of complex biological molecules.

Beyond food and pharmaceuticals, Potassium Sodium Tartrate finds significant applications in industrial processes. Its use in electroplating, especially in copper baths, is highly valued for increasing conductivity, improving anodic solubility, enhancing cathode efficiency, and ensuring greater surface uniformity in plating. It functions as a reducing agent in the silvering of mirrors, producing a brilliant reflective surface. Historically, its notable piezoelectric effect – the ability to generate an electric charge under mechanical stress – led to its use in early electro-acoustic transducers like microphones and phonograph pickups. Other applications include its role as a reducing agent in the thermos industry, a retardant for wall plaster and cement, and even in cigarette paper to control burn rates. Its versatility makes it a preferred choice for various metal treatments and gas purification processes.
