Quality Control

Our 4-Fluoro-2-Methyl-Dl-Phenylalanine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral analysis, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment to guarantee traceability and consistency.

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 after opening to prevent moisture absorption, which may affect stability and handling properties.
