Technical Specifications

Models and Options

Available in standard electronic grade packaging. Custom isomer ratios and high-purity grades can be developed per client requirements.

Materials and Structure

The product is a chloromethylated styrene derivative with a vinyl group and chloromethyl group, enabling polymerization and further functionalization. It is moisture-sensitive and must be stored in a dry, sealed environment under inert gas.

Applications

Ideal for synthesizing negative photoresist resins (E-beam), advanced packaging dielectric materials, and homogeneous ion-exchange membranes. Also used in ultra-pure water resins and chelating resins.

Customization

Custom isomer ratio development, high-purity variants, and CDMO process development are available. From lab route optimization to industrial scale-up.

Case Study

Leading international semiconductor material company: Achieved mass production for 193nm immersion lithography photoresist with metal impurities <10 ppb, passing verification by a top-tier Korean wafer fab. Annual supply of 5 tons.
