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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
