Used as a fluorescent probe in biochemical and biophysical studies due to its ability to intercalate into DNA. It helps in visualizing nucleic acids in gel electrophoresis and cell imaging. Also employed in the development of antimicrobial and antiparasitic agents, as acridine derivatives show activity against certain bacteria and protozoa. Commonly used in research for mutagenesis studies because of its DNA-intercalating properties. Additionally, serves as a precursor in the synthesis of dyes and pharmaceuticals.
