Information about our Specialty Amines

Spermine and spermidine are both available as their hydrochlorides. Spermine tetrahydrochloride is a clean, white, light-density, powered solid.  Spermidine trihydrochloride is a clean, white, crystalline solid with excellent absorbance properties.  The hydrochlorides are preferred by some researchers for their ease of use and excellent shelf life capabilities. Spermidine is also available as the phosphoric acid derivative known as dispermidine triphosphate hexahydrate. It is a clean, white, powdered solid, and it also offers excellent shelf life time.
