Quality Control

Our (E)-2-Docosenoic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopy, to ensure it meets precise purity and identity specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). This material is easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere (e.g., nitrogen) to maintain product integrity.
