Quality Control

Every batch of 2-Propenoic Acid, 3-(3,4-Dihydroxyphenyl)-, Phenyl Ester is manufactured under a strict quality management system. We provide comprehensive analytical documentation to ensure traceability and compliance with your project requirements. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are supplied with each shipment. Our quality protocols are designed to meet the stringent standards of pharmaceutical and cosmetic ingredient supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 strong oxidizing agents.
