Quality Control

Our Acyclovir Sodium is manufactured and tested to meet high-purity standards suitable for pharmaceutical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to cGMP (Current Good Manufacturing Practice) guidelines, and our quality system ensures traceability and consistency. Specifications are designed to align with major pharmacopeial expectations, and custom purity grades are available to meet specific project 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and potency.
