Quality Control

Our Aspon (Tm) is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing, including assay by HPLC and identification by IR spectroscopy, to ensure it meets stringent purity specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption. Keep away from strong acids and organic solvents.
