Quality Control

Our 1,3,6,9-Tcdd is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); ensure containers are sealed after use to minimize exposure to atmospheric moisture.
