Quality Control

Our 2-(4-Chloro-3-Methylphenoxy)Butanoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
