Bis(3-aminopropyl)amine

Bis(3-aminopropyl)amine (CAS 56-18-8) is a triamine compound also known as dipropylenetriamine, norspermidine, or IBPA. It carries no assigned E-code and is classified under HS code 29252900. The molecule contains three nitrogen centres arranged along a propylene-linked backbone, giving it a defined spacing between amine groups.

In pharmaceutical and biotechnology applications, the compound functions as a solvent and carrier, where its multiple amine groups enable controlled interaction with active substances or biological matrices. It is used in the synthesis of polyamine-based drug conjugates and as a building block in bioactive molecule research, where the precise nitrogen spacing mimics naturally occurring polyamine structures.

The material is supplied as a technical-grade liquid and falls under REACH registration requirements for the European market. Procurement teams should confirm supplier documentation including SDS, CoA, and REACH compliance status. Standard packaging formats for laboratory and industrial quantities are available on request.
