Description

(2-(Acryloyloxy)Ethyl)(4-Benzoylbenzyl)-Dimethylammonium Bromide, 99 is a high-purity, functional quaternary ammonium salt monomer designed for advanced material synthesis. This compound matters for its unique dual functionality, combining a polymerizable acrylate group with a photoactive benzophenone moiety, enabling the creation of smart, cross-linkable polymers. It is essential for R&D and production teams in the photopolymer, advanced coatings, and specialty adhesive industries seeking to engineer materials with specific surface, mechanical, or light-responsive properties.

Application

• Photopolymerization Initiator & Co-monomer: Key component in UV-curable resins, inks, and coatings for rapid, energy-efficient curing.
• Surface Modification Agent: Imparts permanent hydrophilic or antimicrobial properties to polymers, fibers, and membranes.
• Dental & Biomedical Materials: Used in the formulation of light-curable dental composites, bone cements, and biocompatible hydrogel networks.
• Adhesive & Sealant Formulations: Enhances adhesion and cross-linking density in high-performance structural and pressure-sensitive adhesives.
• Lithographic Materials: Employed in the production of photoresists and printing plates for the electronics and graphic arts industries.
• Advanced Composite Materials: Serves as a coupling agent or cross-linker in fiber-reinforced plastics and nanocomposites.

Quality Control

Our (2-(Acryloyloxy)Ethyl)(4-Benzoylbenzyl)-Dimethylammonium Bromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the specified 99% purity grade. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as specified on the label. This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and moisture absorption. Store away from strong oxidizing agents and heat sources.
