Description

Aminoethylpiperazine (CAS 140-31-8 ), commonly abbreviated as AEP, is a bifunctional amine building block carrying both a primary amine and a piperazine ring. This dual reactivity makes it a sought-after intermediate for curing and cross-linking. It is used for biocidal applications across several industrial sectors. In epoxy coatings and adhesives, AEP functions as a curing agent, reacting with epoxy resins to build cross-linked networks with improved flexibility and adhesion. Water treatment formulations use AEP as a building block for synthesizing polymeric biocides and scale inhibitors. These control microbial growth and deposit formation in industrial water systems and polyurethane production. In polymer production, it serves as a chain extender or reactive modifier, influencing final mechanical properties and network density. Sealant and elastomer manufacturers incorporate AEP to tune cure speed in specialty formulations. Aminoethylpiperazine is supplied as a liquid at standard commercial concentrations. Technical grade is the primary market offering, with purity specifications typically at 98% or higher depending on the specific requirement. Packaging ranges from drums to IBC containers, suited to both formulators sourcing in moderate volumes and industrial buyers requiring bulk quantities. This ensures reliable supply chains for various manufacturing scales. Contact us for supply of Aminoethylpiperazine Request Quote
