Propylenediamine is a highly reactive aliphatic dibasic primary amine; the dual amino groups within its molecule confer extremely strong basicity and chelating reactivity. Its downstream applications span five core sectors: fine chemicals, pharmaceuticals, agrochemicals, materials, and water treatment. In the field of polymer materials, it serves as the primary raw material for low-temperature epoxy resin curing agents. It offers fast curing speeds and high cross-linking density, making it suitable for floor coatings, anti-corrosion coatings, and composite material molding, while improving resin adhesion and water resistance. As an intermediate for chelating agents, it can be used to synthesize EDTA-type modified chelates for heavy metal capture in industrial recirculating water, boiler water stabilization, and scale inhibition in oilfield produced water. In the pharmaceutical industry, it is used to synthesize intermediates for antiparasitic drugs and local anesthetics, and to construct heterocyclic drug structures through amine condensation reactions. In the agrochemical sector, it can be used to prepare adjuvants for herbicides and fungicides, enhancing the adhesion and bioavailability of these formulations. It can also serve as a rubber vulcanization accelerator, a corrosion inhibitor for metal pickling, and a color-fixing tanning agent for textiles and leather. In laboratory settings, it functions as a basic titration reagent and a chromatographic analysis aid. Possessing dual properties as both a synthetic carrier and a catalytic aid, it offers strong compatibility and can undergo polycondensation reactions with aldehydes, epoxides, and carboxylic acids, making it an extremely versatile basic amine fine chemical raw material.
