Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It serves in the production of certain herbicides and plant growth regulators due to its aromatic amine structure, which can be modified to achieve specific biological activity. Also utilized in the development of specialty chemicals such as dyes and additives, where the amine group acts as a reactive site for further chemical transformations. Its ethyl-substituted phenyl backbone provides enhanced lipophilicity, making it suitable for applications requiring membrane permeability or solubility in organic phases.
