Quality Control

Our Cetylpyridinium Bromide Hydrate 98 is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets the high standards required for pharmaceutical and industrial applications. A Certificate of Analysis (COA) detailing purity, loss on drying, and other critical parameters is provided with every shipment.

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 absorption of atmospheric moisture.
