Quality Control

Our Cysteamine Hydrochloride is manufactured under strict quality management systems to ensure it meets the rigorous standards required for pharmaceutical applications. Each batch is tested against comprehensive specifications, including identity, purity, and impurity profiles. Certificates of Analysis (COA) are provided, detailing results from advanced analytical techniques. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) upon request, supporting 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
