Description

Sodium Bitartrate is the monosodium salt of L-(+)-tartaric acid, a key organic compound with the CAS registry number 526-94-3. This versatile chemical is prized for its role as a safe and effective acidulant and leavening agent in food systems. It is an essential ingredient for manufacturers in the food and beverage, pharmaceutical, and chemical synthesis industries, where precise pH control and reliable reactivity are required.

Application

• Food & Beverage Industry: Primarily used as a leavening acid in baking powders, where it reacts with sodium bicarbonate to release carbon dioxide. It also serves as a pH control agent and stabilizer in jellies, candies, and beverages.
• Pharmaceuticals: Employed as a mild laxative and as an excipient in effervescent tablet formulations for its predictable acid-release properties.
• Chemical Synthesis: Acts as a chiral resolving agent for the separation of racemic mixtures and as a starting material or intermediate in organic synthesis.
• Laboratory Reagent: Used in analytical chemistry and as a buffer component in various biochemical and diagnostic applications.
• Cleaning & Descaling: Utilized in mild, biodegradable cleaning formulations for removing mineral deposits, such as limescale.
