2-Sulfoethyl methacrylate

2-Sulfoethyl methacrylate (CAS: 10595-80-9) is a highly functional sulfonated methacrylate monomer widely used in polymer synthesis, water treatment technologies, and advanced material development. Featuring a hydrophilic sulfoethyl group and a reactive methacrylate double bond, it enables efficient copolymerization and the introduction of ionic functionality into polymer systems. Its primary applications are outlined below:

1. Polymer Synthesis & Functional Materials

Ionic Copolymer Development

The methacrylate group allows efficient free-radical polymerization and copolymerization with various vinyl monomers, while the sulfonic functionality introduces hydrophilicity and charge density. This makes it ideal for synthesizing water-soluble polymers, polyelectrolytes, and functional copolymers.

Surface Modification & Functional Coatings

2-Sulfoethyl methacrylate is widely used to modify polymer surfaces, enhancing wettability, adhesion, and anti-fouling properties. It is particularly valuable in coatings requiring improved dispersion stability and ionic interaction.

2. Water Treatment & Separation Technologies

Ion-Exchange & Membrane Materials

The sulfonate group enables strong ionic interactions, making this monomer a key building block for ion-exchange resins, filtration membranes, and electro-separation materials used in water purification and wastewater treatment.

Dispersants & Scale Inhibitors

Polymers derived from this compound exhibit excellent dispersing properties and are used in formulations for scale inhibition, sludge control, and stabilization of suspended particles in industrial water systems.

3. Advanced Material & Specialty Applications

Electro-Responsive & Conductive Materials

The presence of ionic groups supports the development of conductive polymers, electro-responsive hydrogels, and materials used in sensors, energy storage, and smart systems.

Hydrophilic Functional Polymers

It is commonly incorporated into hydrogels, adhesives, and biomedical materials to improve water absorption, biocompatibility, and functional performance.

4. Research & Development Applications

Polymer Design & Mechanism Studies

Researchers utilize this monomer to study structure–property relationships in ionic polymers, optimize polymerization conditions, and tailor material performance for specific applications.

Scale-Up & Process Development

Its well-defined structure and reactivity make it suitable for laboratory synthesis, pilot-scale trials, and industrial process optimization, supporting smooth transition from R&D to commercialization.

5. Handling & Storage

Storage Conditions

Store in tightly sealed containers under cool, dry, and light-protected conditions. Due to its hygroscopic nature, exposure to moisture should be minimized. The presence of polymerization inhibitors (e.g., MEHQ) is recommended to maintain stability during storage and transport.

Intended Use

2-Sulfoethyl methacrylate is intended for research, development, and industrial applications. It is not for direct pharmaceutical or food use without appropriate regulatory compliance.

Summary

The value of 2-Sulfoethyl methacrylate lies in its unique combination of a polymerizable methacrylate group and a strongly hydrophilic sulfonate functionality. This dual characteristic enables the design of advanced ionic polymers, functional coatings, and separation materials, supporting innovation in water treatment, material science, and specialty chemical applications.
