Quality Control

Our Triundecylamine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and identification by FT-IR, to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed-upon standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
