Quality Control

Our 3-(Dodecylthio)Propylamine is manufactured under a rigorous quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC or titration and identification by FTIR, to ensure it meets precise chemical and physical specifications. We provide full traceability and Certificates of Analysis (COA) 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 at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
