Product Overview

• Diisopropyl ethylamine (DIPEA), also known as Hünig’s base, is a sterically hindered tertiary amine with low nucleophilicity.
       • It is widely used as a non-nucleophilic base in organic synthesis and offers excellent selectivity in acylation and other base-mediated reactions.
       • Typically supplied as a colorless liquid with a mild amine odor.

Key Applications

• Peptide synthesis: common base in coupling reactions
• Organic synthesis: acylation, alkylation, esterification where non-nucleophilic base is required
• Fine chemicals: used as base and catalyst in specialty syntheses
• Industrial: applicable as additive or neutralizing agent in formulations
