Quality Control

Our Phenyl 4-Chlorobutyrate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed to minimize moisture absorption and volatilization.
