What is WANG RESIN

WANG RESIN is a high-performance, versatile polymer material designed for a wide range of industrial and commercial applications. Known for its exceptional durability, chemical resistance, and thermal stability, WANG RESIN is ideal for use in coatings, adhesives, composites, and 3D printing. Its unique formulation ensures excellent adhesion, flexibility, and strength, making it a preferred choice for demanding environments. Whether used in automotive, construction, electronics, or consumer goods, WANG RESIN delivers consistent quality and reliability. Environmentally conscious, it is also available in eco-friendly variants, aligning with sustainable manufacturing practices. With WANG RESIN, industries can achieve superior performance while meeting modern challenges.

Preparation Process: To prepare Wang resin (4-hydroxymethylphenoxymethyl polystyrene resin), follow these steps: 1. **Chloromethylation**: Treat polystyrene resin (1% DVB cross-linked) with chloromethyl methyl ether and a Lewis acid (e.g., SnCl₄) to form chloromethylated polystyrene. 2. **Hydroxymethylation**: React the chloromethylated resin with 4-hydroxybenzyl alcohol in the presence of a base (e.g., K₂CO₃) in DMF at 60–80°C for 12–24 hours. 3. **Washing and Drying**: Wash the resin sequentially with DMF, methanol, and dichloromethane, then dry under vacuum. The resulting Wang resin is ready for solid-phase peptide synthesis.

Usage Scenarios: WANG RESIN is a solid-phase support used in peptide synthesis, particularly for the production of C-terminal amide peptides. It is a polystyrene-based resin functionalized with a 4-hydroxymethylphenoxyacetic acid linker, enabling efficient attachment of the first amino acid via an ester bond. The resin is compatible with Fmoc (9-fluorenylmethoxycarbonyl) chemistry, allowing stepwise peptide chain elongation. Its acid-labile linker facilitates cleavage under mild conditions (e.g., trifluoroacetic acid), releasing the peptide while preserving side-chain protections. WANG RESIN is favored for its stability during synthesis and high loading capacity, making it suitable for automated and manual peptide synthesis of moderate-length sequences.
