Isopropylamine is widely used as an intermediate in the synthesis of agrochemicals, particularly herbicides and pesticides. It serves as a building block for compounds like atrazine and simazine, which are effective in controlling broadleaf and grassy weeds in agriculture.

It is also employed in the production of pharmaceuticals, where it acts as a precursor in the manufacture of certain analgesics and antipyretics. Its reactivity makes it valuable in forming amide and imine derivatives used in drug development.

In industrial applications, isopropylamine functions as a corrosion inhibitor and a flotation agent in ore processing. It is used in water treatment systems to control pH and prevent metal degradation.

Additionally, it serves as a solvent or catalyst in organic reactions, especially in the production of rubber chemicals and dyes. Due to its basic nature, it is effective in acid neutralization and in promoting condensation reactions.
