Quality Control

Our Cilostamide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity, suitable for research and pharmaceutical applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards, and custom synthesis or specific purity grades (e.g., >98%, >99%) are available to meet your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and performance.
