Quality Control

Every batch of 6,7-Difluoronaphthalene-2-Carbaldehyde is produced under strict quality management protocols. We ensure compliance with relevant industry standards through rigorous analytical testing, including HPLC, GC, NMR, and IR spectroscopy for identity and purity verification. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
