Quality Control

Our Gemifloxacin Mesylate is manufactured and tested to meet high-purity pharmacopeial standards. Each batch undergoes comprehensive analytical testing, including identification, assay, impurity profiling, and residual solvent analysis. A Certificate of Analysis (COA) documenting all test results against predefined specifications is provided with every shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. The container should be kept tightly sealed when not in use.
