Quality Control

Our Djenkolic Acid is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation by IR and NMR, purity assessment by HPLC, and specific tests for related substances and residual solvents. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
