Sodium Phosphate Monobasic Monohydrate is a chemical compound that is commonly known as monosodium phosphate monohydrate or sodium dihydrogen phosphate monohydrate.

In the life science field, it is primarily used as a buffering agent and as a source of phosphate ions. Buffers help maintain a stable pH in biological and biochemical processes, ensuring optimal conditions for enzymatic reactions, cell culture, and other molecular biology techniques.

Sodium Phosphate Monobasic Monohydrate is commonly employed in laboratory settings for the preparation of buffer solutions with specific pH ranges and buffering capacities. It is particularly useful in applications where a lower pH range is desired, as it has a buffering capacity in the acidic pH range.

Moreover, the compound is used in various biological and biochemical assays, protein purification processes, and the formulation of diagnostic kits and pharmaceutical products. It serves as a source of phosphate ions, which are essential for numerous biological processes such as DNA and RNA synthesis, energy metabolism, and signal transduction.
