Quality Control

Our Isoperisone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, residual solvent analysis, and identification by IR and NMR, to ensure it meets high-grade pharmaceutical standards. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support compliance with GMP, ICH Q7 guidelines, and relevant pharmacopoeial requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
