Quality Control

Our n-Heptadecylpropane-1,3-Diamine is manufactured 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 specifications for purity, color, and amine value. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong oxidizing agents and acids.
