Sodium 3-hydroxybutanoate(CAS: 150-83-4)

Sodium 3-hydroxybutanoate, with the CAS number 150-83-4, is a sodium salt of 3-hydroxybutanoic acid. It is a white crystalline solid that is soluble in water and commonly used in various chemical applications. This compound has a molecular formula of C4H8NaO3 and is known for its hygroscopic nature and ability to act as a chelating agent.

Sodium 3-hydroxybutanoate is primarily used in pharmaceuticals as a preservative and stabilizer. It also finds applications in food preservation, industrial processes, and research settings. Its chelating properties make it useful in preventing metal ion catalyzed reactions, enhancing product shelf life, and maintaining chemical stability in formulations.

Sodium 3-hydroxybutanoate is generally considered safe when handled properly. However, it is important to follow safety guidelines to avoid exposure to skin, eyes, or inhalation. Protective measures such as gloves, safety goggles, and a well-ventilated environment are recommended. It is non-toxic in normal use but may cause irritation if mishandled.

Sodium 3-hydroxybutanoate should be stored in a cool, dry place away from direct light. It is hygroscopic and should be kept in a sealed container to prevent moisture absorption. Storage at temperatures below 25°C and in a controlled humidity environment is recommended to maintain its stability and effectiveness.
