Miscible with water and ethanol.


N-Ethyldiisopropylamine is used to make or formulate industrial products. It is also used in organic chemistry as a base. It acts as a selective reagent in the alkylation of secondary amines to tertiary amines by alkyl halides. It reacts with monoactivated Michael acceptors to afford symmetrical sulfones. Further, it is used to prepare heterocyclic compound, sscorpionine by a reaction with disulfur dichloride using 1,4-diazabicyclo[2.2.2]octane (DABCO) as a catalyst.


Incompatible with acids, acid chlorides, acid anhydrides, carbon dioxide, copper, brass, rubber, oxidizing agents, nitrates, peroxides, aldehydes and metals.
