Sodium dihydrogen phosphate(CAS: 7632-05-5)

Sodium dihydrogen phosphate (CAS: 7632-05-5) is a white crystalline solid with a molecular weight of 120.04 g/mol. It has a solubility of 142 g/100 mL water at 25°C and is slightly soluble in ethanol. Chemically, it is an ionic compound that reacts with bases to form sodium phosphate and with acids to release phosphoric acid. It is stable under normal conditions but should be stored in a cool, dry place away from direct sunlight.

Sodium dihydrogen phosphate is typically synthesized by reacting sodium hydroxide with phosphoric acid. The reaction can occur in a two-step process: first, sodium phosphate is formed, and then it is treated with hydrochloric acid to produce sodium dihydrogen phosphate. This process has a yield of around 95%, and no specific catalysts are required.

Sodium dihydrogen phosphate (CAS: 7632-05-5) is widely used in the pharmaceutical, food, and chemical industries. It serves as a buffer in pharmaceutical formulations, a leavening agent in food processing, and a component in various chemical reactions. Additionally, it is used in the production of fertilizers and water treatment processes.

When handling sodium dihydrogen phosphate (CAS: 7632-05-5), it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Store it in a cool, dry place away from direct sunlight and flammable materials. In case of a spill, use appropriate tools to clean it up and dispose of it according to local regulations. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information.
