TES, hemisodium salt (CAS 7365-44-8 (non-salt))

Sinónimo:	N-tris(Hydroxymethyl)methyl-2-aminoethanesulfonic acid
Solicitud:	A structural analog to Tris buffer useful for a variety of biological applications
Número CAS:	7365-44-8 (non-salt)

Descripción

TES is a structural analog to Tris buffer, one of the ethanesulfonic acid series of biological buffers developed by Good et al. Good’s buffer 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. TES probably exists in solution as a zwitterion. Because the pKa is 7.4 (physiological pH) this buffer has considerable potential for a variety of biological applications.
