Quality Control

Every batch of 3-[(3-Acrylamidopropyl)Dimethylammonio]Propanoate is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemicals and monomers used in research and specialty polymer synthesis. Comprehensive testing includes identity confirmation, purity assay, and critical impurity profiling. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment and is 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 (15-25°C). 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 moisture absorption and oxidation. Keep away from heat, sparks, and open flame.
