Quality Control

Every batch of 2,4-Pentadienoic Acid, 4-Hydroxy- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and conformance to agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
