Quality Control

Every batch of 2-(4-Chlorophenoxy)Butanoyl Chloride is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for sensitive synthesis applications. Comprehensive analytical testing, including chromatography and spectroscopy, is performed. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to support your quality and regulatory requirements.

Storage

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