Quality Control

Our 2-Chloro-4-Bromobenzaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and spectroscopic identification (IR, NMR), to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
