Quality Control

Our Propanoic Acid, 3-[2-(2-Carboxyethoxy)Ethoxy]-, 1-Methyl Ester is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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, the container must be kept sealed under dry conditions to prevent degradation. Keep away from strong acids and organic solvents.
