Ethyl 4-amino-2-fluorobenzoate is primarily used as an intermediate in the synthesis of more complex chemical compounds. It plays a significant role in the development of pharmaceuticals, particularly in the creation of active pharmaceutical ingredients (APIs) that require a fluorinated aromatic structure. The compound is also utilized in organic chemistry research for the preparation of various heterocyclic compounds, which are often explored for their potential biological activities. Additionally, it serves as a building block in the production of dyes and pigments, where its fluorinated aromatic ring contributes to the stability and unique properties of the final product. Its application extends to agrochemicals, where it is used in the synthesis of herbicides and pesticides, leveraging its structural properties to enhance efficacy and selectivity.
