What is 4-Morpholineethanesulfonic Acid/MES with CAS 4432-31-9?


MES (2-Morpholinoethanesulphonic acid) is a zwitterionic buffer effective in the pH range 5.5-7.7. As a Good’s buffer, MES is widely used to adjust pH in plant culture media, reagent solutions, and physiological experiments. It is a light yellow paste. Flash point 149℃, pour point 60℃. Water solubility 1% at 25℃. It has high detergency, excellent calcium soap dispersion and hard water resistance. Good biosolubility.
