Quality Control

Our Famciclovir is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity pharmacopeial standards, including identification, assay, and impurity profile checks. Certificates of Analysis (COA) detailing results for purity, related substances, residual solvents, and heavy metals are provided to guarantee compliance with cGMP and ICH guidelines for pharmaceutical ingredients.

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. For long-term storage, consider using desiccants.
