Quality Control

Our production of 2-Propenoic Acid, 3-(3,4-Dihydroxyphenyl)-, Propyl Ester adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment.

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 compound, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation, especially after opening the primary container. Keep away from strong oxidizing agents.
