This compound is primarily utilized in the field of organic synthesis, where it serves as a key intermediate in the production of more complex quinoline derivatives. These derivatives are often explored for their potential pharmacological activities, including antimicrobial, anticancer, and anti-inflammatory properties. Additionally, it is used in the development of fluorescent dyes and sensors due to its quinoline backbone, which is known for its photophysical properties. Researchers also employ it in the study of chemical reactions and mechanisms, particularly those involving brominated and ethoxy-substituted heterocycles.
