Quality Control

Our Icosan-1-Yl Hydrogen Sulphate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC/Titration), identification (IR), and control of key impurities, to ensure consistent purity and performance. Certificates of Analysis (COA) documenting all test results are provided and available upon request to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product quality and stability.
