Quality Control

Our Clavaserine is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, spectroscopic identification (IR, NMR), and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 may affect stability and purity. For long-term storage, consider using desiccants.
