Reagent/Compendial
ICH-Q7 GMP Manufactured ProductTROMETHAMINE (TRIS)
99.9% High Purity, USP, Reagent GMP Grade
Low Bioburden, Low Endotoxin, Multicompendial, GMP Manufactured,
Reagent Grade Product
Product Code: TRIS-3257 | Previously: TR3257
Intended For Use As A High Purity Reagent Grade
For Critical Analytical, Diagnostic and Pharmaceutical Applications, and downstream manufacture of drug products where a high purity, high assay, GMP Tromethamine is required. Tris is a considered a “Good’s” buffer because it has low UV absorptivity, minimum reactivity, stable pH and is soluble in water.
