Used primarily as an intermediate in organic synthesis, especially in the production of agrochemicals and pharmaceuticals. Its chiral structure makes it valuable for creating enantioselective compounds, where the (S)-configuration influences biological activity. It participates in urethane and urea formation, useful in developing specialty polymers with tailored properties. Also employed in the synthesis of bioactive molecules, including insecticides and plant growth regulators, due to its lipophilic nonyl chain and reactivity of the isocyanate group. Handle with care—highly reactive and moisture-sensitive.
