Introduction to CAS 87-69-4

CAS 87-69-4 refers to L-Tartaric Acid, a naturally occurring organic acid known for its role in various industrial applications. It is widely found in plants, particularly in grapes, bananas, and tamarinds. Tartaric acid appears as a white crystalline powder and is water-soluble. The acid is characterized by its chiral molecular structure and a chemical formula of C₄H₆O₆, with a molar mass of 150.087 g/mol.

Applications of CAS 87-69-4

L-Tartaric Acid is utilized across multiple industries due to its unique properties. The following are key applications:

• Food and Beverage Industry: It is used as an acidulant and natural preservative. The European Union has assigned E number E334 to it for food additive purposes. It enhances flavors, improves the stability of emulsions, and maintains the pH level in drinks.
• Pharmaceuticals: Tartaric acid acts as an excipient in pharmaceutical formulations. It is employed in pH adjustment and stabilization of active pharmaceutical ingredients (APIs). Its role is crucial in solubility enhancement and optically active enantiomer formulations.
• Construction: It is incorporated in gypsum and cement additives to slow the setting rate, improving workability and strength.
• Cosmetics: It aids in the formulation of skin-care products by acting as an exfoliant and pH balancer.
• Textiles: In textile processing, it is a component in mordant dyeing, enhancing dye uptake and fixation.
