Quality Control

Our 4-Bromo-3-Chloro-Benzaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment. We are committed to meeting the stringent requirements of cGMP and ISO standards for advanced chemical intermediates.

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). This material is light-sensitive and easily oxidized; for long-term storage, consider under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal purity. Keep away from strong oxidizing agents and bases.
