2--(N-morpholino)ethanesulfonic acid, CAS 4432-31-9 [1][2][3]. Stable pH vs. temperature, no primary amine groups, no metal chelation, near physiologic pH range.
- pKa at 25C of 6.10 (5.97 at 37C)
- usable buffering range of 5.5 to 6.7
- molecular weight 195.24
- ΔpKa/ΔT = -.011
Buffers are typically 1 M, prepared by neutralizing MES with sodium hydroxide.
