Piperazine

Piperazine (CAS 110-85-0) is a cyclic diamine supplied as crystalline flakes, also known under trade names including Antepan, Antiren, Dispermine, and Lumbrical. It carries no assigned E-code and is classified under the amines category with EC number 203-808-3 and formula C4H10N2.

In plastics and polymer manufacturing, piperazine functions as a crosslinker by reacting with epoxy or isocyanate groups to form covalent network structures that improve mechanical and thermal performance. In pharmaceutical synthesis and agrochemical production, it serves as a catalyst and key building block, accelerating reaction pathways through its dual secondary amine sites.

Piperazine is available in pharmaceutical-grade forms compliant with Ph.Eur. standards and in technical grades for industrial applications, both subject to REACH registration requirements. Standard packaging includes multi-layer bags and fiber drums. Procurement teams should confirm grade specification against intended application prior to ordering.
