Sodium propionate(CAS: 137-40-6)

Sodium propionate is an organic compound with the chemical formula C3H6NaO2. It is a sodium salt of propionic acid and appears as a white crystalline solid. It is soluble in water and has a mild, salty odor. Sodium propionate is commonly used as a preservative and acidulant in various industries, including food and pharmaceuticals.

Sodium propionate is primarily used as a preservative in food to inhibit mold and yeast growth. It also serves as a buffer in pharmaceuticals and is used in the production of plastics and textiles. In research, it functions as a reagent in organic synthesis. Additionally, it is employed in the manufacturing of certain dyes and coatings due to its chemical properties.

Sodium propionate is generally considered safe when used in recommended amounts. It is approved by regulatory bodies such as the FDA for food use and has low toxicity. However, proper handling is essential to avoid inhalation or skin contact. Safety data sheets (SDS) recommend using protective gloves and eyewear during handling to ensure safe exposure.

Sodium propionate should be stored in a cool, dry, and well-ventilated area, away from direct sunlight. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption. Proper storage ensures its chemical integrity and prolongs shelf life, making it suitable for use in food, pharmaceutical, and industrial applications.
