Description and Uses

Diisopropylamine is a secondary amine and is a colorless liquid at room temperature with a fishy, ammonia-like odor. It is used as a chemical intermediate, and catalyst for the synthesis of pesticides and pharmaceuticals. Diisopropylamine is associated with tobacco either as a natural component of tobacco, pyrolysis product (in tobacco smoke), or additive for one or more types of tobacco products. Synonyms for diisopropylamine include DIPA, and N-(1-methylethyl)-2- propanamine.

Diisopropylamine is used as a precursor to prepare lithium diisopropylamide and sulfenamides, which are used in rubber vulcanization. It is also involved in the synthesis of N,N-Diisopropylethylamine (Hünig's base) obtained by alkylation with diethyl sulfate. Diisopropylammonium bromide is a bromide salt of DIPA used as an inert alternative to barium titanate. It is widely used as solvent as well as an intermediate in the the synthesis of pharmaceuticals, dyes, mineral flotation agents and emulsifiers.
