Sodium Phosphate Monobasic Monohydrate, also known as monosodium phosphate monohydrate, is widely used as a buffering agent and phosphate source in life science research. It maintains stable pH in acidic ranges, supporting enzymatic reactions, cell culture, and molecular biology techniques. Common applications include buffer preparation, protein purification, biochemical assays, and diagnostic kit formulation. The phosphate ions it provides are vital for biological processes such as DNA/RNA synthesis, energy metabolism, and signal transduction, making it essential in biochemical and pharmaceutical research.
