Description

General description

Diisopropylamine (DIPA) is an aliphatic secondary amine widely used as an organic base in organic synthesis. Its standard molar enthalpy of formation and combustion has been measured by static-bomb calorimetry.

Application

Diisopropylamine (DIPA) may be used in the following syntheses:

• diisopropylamine methyl urea (DMU)
• N,N-diisopropyl quinoline-2-carboxamide
• 3-N-sulfonylamidine coumarins
• N-chloroamine, an intermediate to generate amides
