Quality Control

Every batch of 4-Naphthalen-1-Yl-3-Oxo-Butyric Acid Ethyl Ester is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
