Description

2-Acrylamide-2-Methylpropanesulfonic Acid (CAS NO 15214-89-8) is a high-purity, sulfonic acid-functionalized vinyl monomer renowned for its exceptional water solubility and anionic character. This compound is a critical building block for synthesizing advanced polymers with superior thermal stability, salt tolerance, and resistance to hydrolysis. It is essential for manufacturers in the water treatment, oilfield chemicals, personal care, and textile industries seeking to enhance product performance under demanding conditions.

Application

• Water Treatment Polymers: A key monomer for scale and corrosion inhibitors, dispersants, and flocculants in industrial cooling, boiler, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling muds, friction reducers, and enhanced oil recovery (EOR) polymers for high-temperature, high-salinity environments.
• Personal Care & Cosmetics: Imparts anti-static properties, clarity, and film-forming characteristics in hair gels, styling mousses, and skin care formulations.
• Textile & Fiber Sizing: Enhances the adhesion, strength, and dye receptivity of sizing agents and coatings for synthetic fibers.
• Superabsorbent Polymers (SAPs): Incorporated to improve the absorption rate and gel strength in hygiene and agricultural products.
• Coatings & Adhesives: Serves as a reactive monomer to improve adhesion, dispersibility, and rheological properties in aqueous formulations.
• Paper Manufacturing: Used in retention aids, drainage aids, and dry/wet strength resins to improve paper quality and production efficiency.

Quality Control

Our 2-Acrylamide-2-Methylpropanesulfonic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
