L(+)-Tartaric Acid
1. Basic Information
Name: L(+)-Tartaric Acid
Alias: (2R,3R)-2,3-Dihydroxybutanedioic acid
CAS No.: 87-69-4
Molecular Formula: C4H6O6
Molecular Weight: 150.09
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless transparent monoclinic crystal or white crystalline powder
- Odor: Odorless, strong sour taste
- Solubility: Freely soluble in H2O, soluble in CH3OH, slightly soluble in C2H5OH, insoluble in acetone and aliphatic hydrocarbons
- Melting Point: 168–170 °C
- Hygroscopicity: Slightly hygroscopic under high humidity
- Aqueous Characteristic: Strongly acidic aqueous solution with good metal chelating capacity
Chemical Properties
- Molecular Structure: Chiral dicarboxylic acid containing two hydroxyl groups on adjacent carbon atoms
- Acid-base Reaction: Reacts with alkalis, carbonates to form tartrate salts such as potassium bitartrate and sodium tartrate
- Chelating Performance: Forms stable soluble complexes with metal ions including Ca2?, Fe3?, Cu2?
- Thermal Stability: Stable below 100 °C; decomposes above melting point to generate carbon dioxide and caramelized impurities
- Photostability: Completely stable under light without discoloration or degradation
- Compatibility: Compatible with most food raw materials and cosmetic ingredients; incompatible with strong oxidants
3. Main Application Fields
1. Food & Beverage Additive (Core Application)
- Acidity regulator for wine, juice, candy, baking products to adjust sour taste and improve flavor
- Antioxidant synergist and color stabilizer for fruit processed food
2. Pharmaceutical Raw Material
Excipient for effervescent tablets; raw material for preparation of tartrate drug salts
3. Cosmetic & Daily Chemical Auxiliary
Skin exfoliating AHA ingredient; chelating agent to shield metal ions and prevent formula discoloration
4. Electroplating & Chemical Industry

Safety Warning
Acidic crystalline powder. Dust irritates eyes, nasal mucosa and skin; long-term skin contact may cause mild corrosive irritation. Wear dust mask, acid-resistant gloves and protective goggles during operation with ventilation. Avoid mixing with strong alkaline materials to prevent neutralization heat release. Waste liquid requires neutralization treatment before discharge; solid waste can be disposed as general organic solid waste.
