Quality Control

Our 3-Fluoro-4-Methoxyaniline Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR and IR for structural confirmation, and rigorous control of residual solvents and heavy metals. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with your research or production specifications.

Storage

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