Product Description:

2-Morpholinoethanesulfonic acid hydrate (MES hydrate, CAS 145224-94-8) is a zwitterionic buffer compound structurally composed of a morpholine ring and an ethanesulfonic acid group. It is a hydrated form of MES, commonly used in biochemical and molecular biology research. Its primary application is as a biological buffer, particularly effective in the pH range of 5.5 to 6.7. MES is widely utilized in cell culture media, protein purification, and enzymatic assays due to its minimal interference with biological systems and low metal ion binding. It is also employed as a standard reagent in analytical chemistry for pH calibration and titration.
