Quality Control

Our Isoquinolinium Chloride is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Each lot is subjected to comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) detailing all test results are provided with every shipment and are available upon request to support your quality assurance protocols.

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 to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials.
