Quality Control

Our 2-Bromo-4-Chloro-1-(2,5-Difluorophenyl)Butan-1-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
