Description

(2-Hydroxy-3-Methacryloxypropyl) Trimethylammonium Chloride is a versatile quaternary ammonium methacrylate monomer, a key building block for imparting permanent cationic functionality to polymers. Its primary value lies in its ability to introduce a positive charge and a polymerizable methacrylate group, enabling the synthesis of materials with enhanced adhesion, antimicrobial properties, and compatibility with aqueous systems. This compound is essential for formulators and polymer chemists in the water treatment, personal care, biomedical, and specialty coatings industries seeking to develop advanced functional materials.

Application

• Flocculants and Coagulants: A key monomer for synthesizing cationic polyacrylamides (CPAM) used in municipal and industrial wastewater treatment, papermaking, and mining.
• Antimicrobial Polymers: Used to create contact-killing surfaces, coatings, and resins for medical devices, textiles, and hygienic applications.
• Hair and Skin Care Products: Incorporated into conditioning polymers for shampoos and lotions to provide substantivity and a soft feel.
• Adhesion Promoters: Enhances the bonding of coatings, inks, and adhesives to challenging anionic substrates like glass, metals, and plastics.
• Ion Exchange Resins: Serves as a functional monomer for producing strong base anion exchange resins.
• Enhanced Oil Recovery (EOR): Used in polymers that modify the rheology of injection water to improve oil displacement.
• Dental and Biomedical Materials: Imparts hydrophilic and bioactive properties to dental composites, bone cements, and drug delivery systems.
• Paper Sizing and Retention Aids: Improves the retention of fillers and fines in paper manufacturing processes.

Quality Control

Our production of (2-Hydroxy-3-Methacryloxypropyl) Trimethylammonium Chloride adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and color are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and stability. Keep away from incompatible materials such as strong oxidizing agents.
