Sodium citrate monobasic (monosodium citrate) is primarily used in the food and beverage industry as an acidity regulator, buffering agent, and emulsifier. It helps maintain pH levels and stabilize emulsions in products such as cheeses, beverages, and processed foods, contributing to consistent texture and flavor. In pharmaceuticals, it serves as a buffering agent in formulations and as a sequestrant to bind metal ions. Its chelating properties also make it suitable for use in cleaning products and water treatment to remove hardness and prevent scale formation. Note: Unlike trisodium citrate, it is not commonly used as an anticoagulant or for urine alkalization in kidney stone management.
