N-(3-aminopropyl)-2-pyrrolidinone

N-(3-aminopropyl)-2-pyrrolidinone is a bifunctional pyrrolidone derivative combining a polar lactam ring with a reactive primary amine. This structure gives it high water solubility, strong hydrogen-bonding capacity, and chemical reactivity, making it primarily useful as an intermediate rather than a finished product. Its design is related to common industrial pyrrolidones (e.g., NMP), but the added amine enables covalent bonding and further functionalization. It can also be used as a precursor for bioactive heterocycles and a building block for drug candidates.

Industrially, it is used mainly in polymer, resin, and coating applications as a reactive intermediate, adhesion promoter, or functional additive, where it improves polarity, compatibility, and surface adhesion. It also serves as a fine chemical and pharmaceutical intermediate, and in specialty formulations (including agrochemical additives) where enhanced solubility and reactivity are desired.
