Quality Control

Our Alexidine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications suitable for pharmaceutical and high-grade industrial applications. A Certificate of Analysis (COA) documenting identity, purity, and related substances is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 absorption of atmospheric moisture.
