Quality Control

Our n-Octadecyl-Trimethyl-Ammonium-3-Hydroxy-2-Naphthoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and degradation.
