Description

2-(Methacryloyloxy)Ethylammonium Hydrogen Sulphate is a specialized quaternary ammonium salt monomer with a reactive methacrylate group. This compound is a key intermediate for synthesizing cationic polymers with permanent positive charges, offering significant value in applications requiring strong ionic interactions and adhesion. It is primarily needed by manufacturers in the water treatment, personal care, coatings, and textile industries for creating flocculants, conditioning agents, and antimicrobial surfaces.

Application

• Cationic Flocculant Synthesis: A crucial monomer for producing high-performance cationic polyacrylamides and other polymers used in municipal and industrial wastewater treatment for sludge dewatering and clarification.
• Hair and Skin Care Products: Used in the formulation of cationic conditioning polymers for shampoos, conditioners, and creams, providing excellent substantivity to hair and skin.
• Antimicrobial Coatings and Finishes: Serves as a building block for polymers used in creating durable antimicrobial surfaces for medical devices, textiles, and industrial equipment.
• Paper Manufacturing: Employed in the production of wet-strength resins and retention aids to improve paper quality and production efficiency.
• Textile Auxiliaries: Used to synthesize cationic softeners, dye-fixing agents, and antistatic agents for fabrics.
• Enhanced Oil Recovery (EOR): A component in formulating polymers that modify the viscosity of injection water to improve oil displacement in reservoirs.
• Adhesive and Sealant Formulations: Imparts cationic character and improved adhesion to various substrates in specialty adhesive systems.

Quality Control

Our 2-(Methacryloyloxy)Ethylammonium Hydrogen Sulphate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
