FAQ

What is Tartaric acid (CAS: 868-14-4)?

Tartaric acid (CAS: 868-14-4) is a dicarboxylic acid with the chemical formula C4H6O6. It is naturally found in many fruits, particularly grapes, and is known for its tart taste. Tartaric acid is a white crystalline solid that is soluble in water and has a melting point around 170°C. It is commonly used in various industries due to its unique chemical properties and chiral characteristics.

What are the main uses of Tartaric acid (CAS: 868-14-4)?

Tartaric acid (CAS: 868-14-4) is widely used in the food industry as a souring agent and antioxidant. It also serves as a key component in pharmaceuticals, particularly in the production of certain drugs and as a stabilizer. In the wine industry, it is used to adjust acidity and enhance flavor. Additionally, it finds applications in the production of synthetic materials, as a chelating agent, and in research for studying stereochemistry and chemical reactions.

Is Tartaric acid (CAS: 868-14-4) safe?

Tartaric acid (CAS: 868-14-4) is generally considered safe when used in appropriate amounts. It is approved by the FDA for use in food and is non-toxic in moderate quantities. However, high concentrations may cause irritation to the skin, eyes, or respiratory system. Proper handling, such as wearing gloves and protective eyewear, is recommended. It is important to follow safety guidelines and storage requirements to ensure safe use in laboratories and industrial settings.

How should Tartaric acid (CAS: 868-14-4) be stored?

Tartaric acid (CAS: 868-14-4) should be stored in a cool, dry, and well-ventilated place, away from direct sunlight. It is best kept in a sealed container to prevent moisture absorption and maintain stability. The ideal storage temperature is below 25°C, and humidity levels should be low. It is important to store it in a location that is inaccessible to children and not in proximity to incompatible substances to ensure long-term safety and effectiveness.
