Quality Control

Our Cefasabal is manufactured under strict quality management systems to meet the exacting standards of the pharmaceutical industry. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with in-house specifications aligned with ICH guidelines. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your regulatory and quality assurance needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
