Name: 2-[Tris(hydroxymethyl)-methylamino]-ethanesulfonic acid
TES is a structural analog to Tris buffer, one of the ethanesulfonic acid series of biological buffers developed by Good et al. Since the pKa of TES buffer is 7.4 (physiological pH) it has considerable potential for a variety of biological applications.
useful pH range: 6.8 - 8.2
pKa (25°C): 7.40
Warning: For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
