Levofloxacin hydrochloride is a synthetic fluoroquinolone antibiotic and active pharmaceutical ingredient (API) used in the production of medications for treating bacterial infections. It exhibits broad-spectrum activity against Gram-positive and Gram-negative bacteria, including those causing respiratory tract infections (e.g., pneumonia, bronchitis, sinusitis), urinary tract infections, skin and soft tissue infections, and abdominal infections. The compound inhibits bacterial DNA gyrase and topoisomerase IV, thereby preventing DNA replication and bacterial proliferation. This high-purity solid (≥97.5%) is suitable for pharmaceutical manufacturing, research, and development applications.
