Quality Control

Our 2-Amino-4-Ethylphenylamine is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure it meets the high-purity standards required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
