Quality Control

Our production of 4-(4-Chlorophenoxy)-3-Oxo-Butanoic Acid Ethyl Ester adheres to stringent quality management protocols. 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 it meets your specific research or production-grade requirements.

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/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
