• Consistent Quality: Full-process ICP-MS monitoring guarantees batch-to-batch consistency, crucial for electronic-grade applications.
• Custom Isomer Ratio: Available with custom o/m/p isomer ratios to meet specific formulation needs.
• Flexible Supply: Typical volume 500kg - 5 tons per batch for high-purity electronic grade supply, with MOQ starting from 1kg.
• Traceability and Compliance: Full traceability and support for third-party re-inspection (SGS, BV, Intertek).

Technical Specifications

Models and Options

This product is available in the standard electronic grade. Custom isomer ratios (o/m/p) are developed from sample to scale-up production.

Materials and Structure

Chemical structure: 1-(chloromethyl)-3-vinylbenzene. It contains an active acid anhydride group and is extremely sensitive to moisture. It must be stored in an absolutely dry and sealed environment to prevent hydrolysis ring-opening reaction.

Applications

Specifically designed for:

• Negative photoresist resins (including E-beam electron beam photoresist)
• Advanced packaging dielectric materials
• Homogeneous ion-exchange membranes
• Ultra-pure water resins and chelating resins

Customization

We offer custom high-purity VBC isomers for semiconductor material clients, with strict quality requirements: ppb-level metal impurity control, full traceability. We also provide custom o/m/p isomer ratio development per client's specific formulation needs, from sample development to scale-up production.

Case Study

We supplied this electronic grade monomer to a leading international semiconductor material company for 193nm immersion lithography photoresist formulation development. Our product achieved metal impurities <10 ppb, meeting SEMI Grade 4 standards, and helped the client pass verification by a top-tier Korean wafer fab and achieve mass production. The microchannel continuous flow technology enabled high-purity production; process optimization and first validation sample delivery completed within 2 weeks.
