Quality Control

Our cis-Caffeic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FTIR and NMR, to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) documenting all test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
