3-(N-Morpholino)propanesulfonic acid hemisodium salt, also known as MOPS sodium salt, is a chemical compound commonly used as a buffering agent in biological and biochemical research. It is a white crystalline powder that is highly soluble in water.
MOPS sodium salt has a chemical formula of C7H14NNaO4S and a molecular weight of 239.24 g/mol. It is structurally similar to the compound MOPS (3-(N-morpholino)propanesulfonic acid), but with the addition of a sodium ion, which improves its solubility and enhances its buffering properties. MOPS sodium salt is frequently used as a buffering agent in applications that require a pH range of 6.5 to 7.9. It has a pKa value of 7.2, making it highly effective in maintaining a stable pH within this range.
In addition to buffering, MOPS sodium salt can also stabilize enzymes and proteins, preserving their activity and structure. It is commonly used in cell culture, protein purification, and molecular biology experiments. When using MOPS sodium salt as a buffer, it is important to accurately measure and prepare the solution to achieve the desired pH. Calibrated pH meters or pH indicators are commonly used to monitor and adjust the pH accordingly.
Overall, MOPS sodium salt is a valuable tool in the laboratory setting, providing a stable pH environment and supporting various biological and biochemical research applications.
