Quality Control

Our 2,4-Difluorophenylurea is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We support compliance with global regulatory frameworks including REACH and can provide material for GMP-grade applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
