Quality Control

Every batch of Benzaldehyde, 4-Hydroxy-2-Iodo- is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for each lot and provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from heat, sparks, and open flame.
