2-Hydroxy-3-(4-morpholinyl)-1-propanesulfonic acid(CAS: 68399-77-9)

2-Hydroxy-3-(4-morpholinyl)-1-propanesulfonic acid, also known as morpholinoacetic acid hydrol, is a colorless to white crystalline powder. Its chemical formula is C7H15NO4S and it has a pKa of approximately 3.4. This compound is amphiprotic and can exist in both acidic and basic forms depending on the pH of the solution.

2-Hydroxy-3-(4-morpholinyl)-1-propanesulfonic acid is primarily used as a chelating agent in pharmaceutical formulations and as a buffer in biochemical and molecular biology research. It is also found in some cleaning agents and metalworking fluids due to its chelating properties and pH buffering capacity.

2-Hydroxy-3-(4-morpholinyl)-1-propanesulfonic acid is generally considered safe for most applications, but it is important to handle it with care. It is non-toxic by ingestion, but skin contact may cause irritation. Users should avoid contact with eyes, inhale dust or fumes, and wear protective gloves and eyewear. It is advisable to work in a well-ventilated area and to dispose of waste in accordance with local regulations.

2-Hydroxy-3-(4-morpholinyl)-1-propanesulfonic acid should be stored in a cool, dry place away from direct sunlight and sources of heat. It should be kept in a tightly sealed container to prevent moisture absorption. The storage temperature should not exceed 25°C. It is important to check the container periodically for signs of moisture or degradation, and to keep it away from incompatible materials such as strong acids or bases.
