DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Diisopropylamine is a common amine nucleophile in organic synthesis. [4] Because it is bulky, it is a more selective nucleophile than other similar amines, such as dimethylamine. [5] It reacts with organolithium reagents to give lithium diisopropylamide (LDA). LDA is a strong, non-nucleophilic base [6]
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.
