Quality Control

Every batch of our Benzaldehyde, 3-Bromo-4-Methoxy-5-Methyl- (9Ci) is produced and controlled under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) that detail purity, identity, and impurity profiles, typically determined by advanced analytical techniques like HPLC, GC, and NMR. Our commitment ensures the material meets the high standards required for research and scale-up applications.

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 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.
