Quality Control

Our trans-2,4-Pentadienoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by HPLC, identification by FT-IR, and impurity profiling, to ensure it meets the high-purity standards required for sensitive applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
