Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. Its structure allows for incorporation into more complex molecules, particularly those requiring cinnamate derivatives with functionalized side chains. It is also employed in the development of UV-absorbing compounds, making it useful in sunscreen formulations and photostabilizers. The amine group enables further derivatization, such as acylation or diazotization, which broadens its utility in creating dyes, fluorescent probes, and bioactive compounds. Additionally, it serves as a building block in the synthesis of certain anticancer and anti-inflammatory agents due to its ability to mimic natural phenolic acids.
