Quality Control

Our 2,5-Dibromoterephthalaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 sensitivity to oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from heat, sparks, and open flames.
