Description

[2-(Methacryloyloxy)Ethyl]Dimethyltetradecylammonium Bromide CAS NO 93963-45-2 is a quaternary ammonium methacrylate monomer, a specialty chemical that combines a polymerizable methacrylate group with a cationic surfactant structure. This unique dual functionality makes it a critical building block for creating materials with permanent antimicrobial, antistatic, or surface-modifying properties. It is primarily sought after by manufacturers in the polymer, coatings, and advanced materials sectors for developing specialty resins, biocidal surfaces, and functional additives.

Application

• Antimicrobial Polymer Synthesis: Key monomer for producing polymers with intrinsic, non-leaching antimicrobial activity for medical devices, coatings, and textiles.
• Surface Modification Coatings: Used to create cationic, surface-active coatings that improve adhesion, wetting, or provide antistatic properties.
• Dental and Biomedical Resins: Incorporated into adhesive systems and restorative materials to impart antibacterial functionality.
• Contact Lens and Hydrogel Materials: Enhances wettability and reduces protein/lipid adsorption in silicone hydrogel formulations.
• Water Treatment Membranes: Functionalizes membrane surfaces to reduce biofouling and improve filtration efficiency.
• Paper and Textile Sizing: Acts as a cationic additive to improve dye retention, strength, and antimicrobial performance.
• Oilfield Chemicals: Used in formulations for clay stabilization, corrosion inhibition, and as a bactericide in drilling fluids.
• Personal Care Polymers: Incorporated into hair fixatives and cosmetic films to provide conditioning and antimicrobial benefits.

Quality Control

Our production of [2-(Methacryloyloxy)Ethyl]Dimethyltetradecylammonium Bromide adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay, residual monomers, and moisture content 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 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 product quality and stability.
