Quality Control

Every batch of 2-Propenoic Acid, 2-Methyl-3-(3,4,5-Trihydroxyphenyl)- (9Ci) is produced and tested under a rigorous quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment. Specifications can be aligned with cGMP or ISO 9001 standards for pharmaceutical development upon request.

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, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain optimal purity and stability. Keep away from heat, sparks, and open flames.
