Quality Control

Every batch of 2-(3-Chlorophenoxy)-2-Methylpropanoyl Chloride is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee consistent quality and traceability for your critical synthesis work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
