Quality Control

Our 4-Fluorophenylurea is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy. We provide full traceability and a detailed Certificate of Analysis (COA) with every shipment, ensuring compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
