Used in dye manufacturing for textiles and leather due to its strong colorant properties. Employed in fluorescence microscopy as a staining agent for nucleic acids, allowing visualization of DNA and RNA in cells. Acts as a building block in synthesizing antiseptic and antimicrobial agents, particularly in topical treatments. Investigated for use in photodynamic therapy for cancer due to its ability to generate reactive oxygen species when exposed to light. Also utilized in research for developing DNA-intercalating compounds that can interfere with tumor cell replication.
