1. Polymer and Materials Science
As a crosslinking agent, used in synthesizing biodegradable polymer networks, liquid crystal elastomers, shape memory materials, etc.
Constructs three-dimensional network structures via “thiol-ene click chemistry,” imparting high mechanical strength, thermal stability, or specialized responsiveness to materials.

2. Specialty Coatings and Adhesives
Formulated into UV-curable coatings, inks, and adhesives.
As modifiers, crosslinkers, or low-temperature curing agents, they enhance coating abrasion resistance, adhesion, weatherability, and curing efficiency.

3. Dental Restoration Materials
Used in synthesizing sulfur-olefin-methacrylate composite resins.
As crosslinking components, they aim to improve traditional dental filling material properties, such as reducing polymerization shrinkage and enhancing durability.

4. Optical Materials
Used in preparing high-refractive-index optical resins, such as optical lenses.
Its molecular structure aids in increasing material refractive index to meet specific optical design requirements.

5. Biomedical & Tissue Engineering
Serves as a crosslinking agent for synthesizing hydrogels or tissue engineering scaffolds.
Leverages its controllable reactivity and good biocompatibility to construct three-dimensional network structures for drug delivery or cell culture.

6. Functional Material Development
Used to develop novel functional materials with properties like photoluminescence and thermoresponsiveness.
Serves as a key reactive building block incorporated into functional polymer systems.

7. Organic Synthesis
Employed as multifunctional intermediates or acidic ion-exchange catalysts.
Provides multiple reactive sites for synthesizing more complex organic molecules or catalyzing specific reactions.
