Quality Control

Our 4-Ethoxy-3-Fluoroaniline is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
