Product Overview

• Diethylhydroxylamine (DEHA) is a widely used hydroxylamine derivative known for its reducing properties. It is commonly applied as an oxygen scavenger in boiler and closed-water systems, a corrosion inhibitor, and a polymerization inhibitor during monomer storage and processing. DEHA helps protect equipment, stabilise monomers and improve product shelf life when used according to recommended procedures.

Key Applications

• Water treatment: oxygen scavenger for boiler and closed-loop systems
• Polymer industry: polymerization inhibitor and stabiliser for monomers
• Chemical synthesis: intermediate and reducing agent in specialty syntheses
• Corrosion control: additive in corrosion protection formulations
