Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the development of potent antimicrobial agents targeting DNA gyrase and topoisomerase IV in bacteria. Its structure enables enhanced penetration into bacterial cells and improved binding affinity, contributing to broad-spectrum activity against Gram-positive and Gram-negative pathogens. Also explored in medicinal chemistry for antiviral and anticancer research due to its ability to modulate enzyme activity and interact with biological targets.
