Quality Control

Our (-)-Cyanopindolol Hemifumarate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing identity, purity, and specific test results are available upon request.

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 should be kept in a desiccated environment to prevent moisture absorption. Keep away from incompatible materials.
