Quality Control

Every batch of 4-(5-Carboxyfuran-2-Yl)Benzaldehyde is manufactured and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and potential for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize repeated exposure to air.
