Quality Control

Our p-Coumaric Acid is produced and tested under stringent quality management systems to meet the exacting requirements of our industrial and research clients. Each batch is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment. We can support compliance needs for various standards, including Food Grade (FCC) and Pharmaceutical (USP/EP) applications upon request.

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 nature as an easily oxidized (store under inert atmosphere) and light-sensitive (store away from light) compound, prolonged exposure to air, moisture, or direct light should be avoided to maintain stability and purity.
