Quality Control

Our 3-[3-(2-Ethoxycarbonyl-Ethoxy)-Propoxy]-Propionic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere such as nitrogen to prevent moisture uptake and potential hydrolysis.
