NNDiisopropylamines

N,N-Diisopropylamines, or N,N-diisopropylamine, are secondary amines in which the nitrogen atom is bonded to two isopropyl groups and one hydrogen. The structure is (CH3)2CH-NH-CH(CH3)2. As a simple dialkylamine, it functions as a versatile building block in organic synthesis and can act as a specialized solvent in certain reactions.

Industrial preparation typically involves controlled exhaustive alkylation of ammonia with isopropyl halides, or related precursors, followed by purification to remove mono- and trialkylated byproducts. Other routes include transamidation or reduction of carbamate-derived intermediates. Because alkylation reactions are exothermic and can produce mixtures, careful temperature control and separation are essential.

Chemically, N,N-diisopropylamine is a moderately basic, nucleophilic secondary amine that forms salts with acids. It is usually a liquid at room temperature and is more soluble in organic solvents than in water, where solubility is limited. It can participate in a variety of transformations, including acylations, condensations, and the formation of amides and related derivatives.

Applications and safety: The amine serves as a chemical intermediate for preparing larger amines, heterocycles, and pharmaceutical building blocks. It can also function as a specialty solvent in some organic syntheses. Handling requires appropriate protective equipment; it can irritate skin, eyes, and the respiratory tract, and it should be stored away from oxidizers and heat in ventilated areas.
