Quality Control

Our Octadecanediamine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters.

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). This material is hygroscopic (moisture-sensitive) and must be kept under dry conditions to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
