Quality Control

Our [2-(Methacryloyloxy)Ethyl]Dimethyl-(3-Sulfopropyl)Ammonium Hydroxide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and compliance with relevant specifications for polymer synthesis. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and reactivity. For long-term storage, consider using desiccants or an inert atmosphere.
