Quality Control

Our Dehydroabietine is produced under a stringent quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, with purity typically exceeding 95% (by HPLC). A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee consistency and traceability for your R&D and production 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). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere such as nitrogen to maintain optimal purity and stability.
