Quality Control

Our (4-Fluoro-3-Methoxyphenyl)Thiourea is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties.
