Quality Control

Our 2-Bromo-4-Chlorobenzaldehyde is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, confirming compliance with customer specifications and relevant industry standards for fine chemical intermediates.

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). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
