Quality Control

Our 4-Bromocinnamaldehyde is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for full traceability and quality assurance.

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 properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to handle under an inert atmosphere such as nitrogen or argon for long-term storage and to minimize exposure to air and light during use.
