Used as an intermediate in the synthesis of fluorogenic probes for detecting reactive oxygen species in biological systems. Its structure allows selective reaction with specific radicals, making it valuable in developing sensors for oxidative stress studies. Also employed in the preparation of quinoline-based antimicrobial agents due to its ability to penetrate cell membranes and interfere with microbial enzyme activity. Shows utility in materials science for designing fluorescent dyes and UV stabilizers in polymers owing to its conjugated aromatic system and strong absorption characteristics.
