描述

TES is a structural analog to Trizma buffer, one of the ethanesulfonic acid series of biological buffers developed by Good et al., to meet these criteria: midrange pKa, maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pKa with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range, and easily synthesized.1 Although the structure above is drawn as a neutral molecule, it probably exists in solution as a zwitterion.
