Quality Control

Our n-Isopropyl-1,3-propanediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is 15-25°C.
