Sodium 4-hydroxybenzoate(CAS: 114-63-6)

Sodium 4-hydroxybenzoate (CAS: 114-63-6) is a white crystalline solid with a molecular weight of approximately 198.15 g/mol. It is slightly soluble in water and more soluble in alcohol. Chemically, it is less reactive compared to its parent compound, benzoic acid, due to the presence of a hydroxyl group. It is stable under normal conditions but may degrade in strongly acidic or basic environments.

Sodium 4-hydroxybenzoate (CAS: 114-63-6) is typically synthesized by the reaction of benzoic acid with sodium hydroxide. The process involves heating a mixture of benzoic acid and sodium hydroxide in aqueous solution. The yield is usually high, and the product is purified by recrystallization from water.

Sodium 4-hydroxybenzoate (CAS: 114-63-6) is primarily used in the pharmaceutical and food industries. It serves as a preservative and antioxidant in food products. In pharmaceuticals, it is used as a raw material in the synthesis of drugs, particularly those requiring a specific pKa or stability under certain conditions.

When handling Sodium 4-hydroxybenzoate (CAS: 114-63-6), appropriate personal protective equipment (PPE) should be worn, including gloves and safety goggles. It should be stored in a cool, dry place, away from strong acids and bases. In case of a spill, it should be cleaned up using appropriate absorbent materials. Always refer to the Safety Data Sheet (SDS) for detailed information on handling and storage.
