ICH-Q7 GMP Manufactured ProductTROMETHAMINE (TRIS)
USP, EP, LBLE (Standard)
GMP Excipient Grade
Low Bioburden, Low Endotoxin, Multicompendial, GMP Manufactured
Product Code: TRIS-3254 | Previously: TR3254
Intended For Use As An Excipient
Tromethamine (Tris), is commonly used as a buffer and excipient in biological applications downstream in the manufacture of drug products. Tris is considered a “Good’s” buffer because it has low UV absorptivity, minimal reactivity, stable pH and is soluble in water.
