Quality Control

Our 2-Ethyl-3-Methyl-1,4-Naphthoquinone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

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 light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal purity and stability. Keep away from heat and incompatible materials.
