Description

Sodium Bitartrate, Monohydrate is the sodium salt of L-(+)-tartaric acid, commonly supplied as a monohydrate crystalline powder. This compound serves as a versatile acidulant, buffering agent, and chiral intermediate in high-value manufacturing processes. It is essential for industries requiring precise pH control, tartrate functionality, or enantiomerically pure building blocks, including food & beverage, pharmaceuticals, and fine chemical synthesis.

Application

• Food & Beverage Additive: Used as a pH regulator, acidulant, and stabilizer in baking powders, beverages, and gelatin desserts.
• Pharmaceutical Excipient: Functions as a buffering agent and tartrate source in tablet formulations and effervescent preparations.
• Chiral Resolution Agent: Employed in the separation of racemic mixtures of amines and other basic compounds due to its enantiomeric purity.
• Chemical Synthesis: Acts as a precursor or catalyst in organic synthesis and as a component in electroplating baths.
• Laboratory Reagent: Serves as a standard or buffer component in analytical chemistry and biochemical research.
