Quality Control

Our 4-Phenoxybutyryl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases, oxidizers, and moisture.
