Quality Control

Our Fleroxacin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC, IR, and residual solvent analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and potency.
