N,N,N′,N′-Tetrakis(2-hydroxypropyl)ethylenediamine

N,N,N′,N′-Tetrakis(2-hydroxypropyl)ethylenediamine (CAS 102-60-3) is a tetrafunctional amino alcohol supplied under trade names including Quadrol, Edetol, and Entprol. It carries no E-code designation and is classified under HS code 29221980 within the broader amines category.

In water treatment, it sequesters calcium and magnesium ions through chelation, preventing scale formation in process systems. In polyurethane formulation, its four hydroxyl groups act as chain extenders and crosslinkers, directly influencing foam density and mechanical properties. It also functions as a pH buffer in pharmaceutical and personal care applications, stabilising formulations in the mildly alkaline range.

The product is available as a technical-grade liquid and, where required, in grades meeting relevant REACH registration obligations for supply within the EU. Packaging is typically offered in drums and IBC containers. Procurement teams should confirm grade specifications and documentation requirements at the point of enquiry.
