Quality Control

Every batch of 1,4-Difluoro-2-Vinyl-Benzene is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee consistent quality and traceability for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent evaporation and potential contamination.
