Used primarily in research settings as a key intermediate in the synthesis of acridine-based compounds, which are known for their biological activity. It serves as a building block in the development of potential therapeutic agents, particularly in neuroscience and oncology. Its structure supports the creation of derivatives that can interact with enzymes such as acetylcholinesterase, making it relevant in studies related to Alzheimer’s disease. Additionally, it is employed in the design of fluorescent probes and DNA-interactive agents due to the inherent properties of the acridine scaffold. Its carboxylic acid functionality allows for easy modification, enabling conjugation to other molecules for targeted drug delivery or biochemical labeling.
