Quality Control

Our 4,4'-Diamino-2,2'-difluorobiphenyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for high-purity monomer applications. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment to guarantee traceability and consistent quality for your production processes.

Storage

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