General description

Tetraethylenepentamine pentahydrochloride (TETRAEN) is an amine salt having five amine groups, which have catalytic roles in various reactions.
Tetraethylenepentamine pentahydrochloride is reported as copper-chelating agent. Regeneration of pancreatic endocrine cells in rats maintained on a copper-deficient diet containing tetraethylenepentamine pentahydrochloride has been reported. It is a high affinity copper and zinc chelator.

Application

Tetraethylenepentamine pentahydrochloride (TETRAEN) has been employed as polyamine catalyst for the bisulfite reaction of cytosine.
Tetraethylenepentamine pentahydrochloride is suitable for in vitro translation, using promega′s flexi rabbit reticulocyte lysate kit.
