Quality Control

Our 4-Methyl-1-Octadecyl-Pyridinium Chloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) documenting purity, physical characteristics, and test results 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
