What Is Bis(4-methacryloylthiophenyl) Sulfide?
Bis(4-methacryloylthiophenyl) Sulfide (CAS 129283-82-5) is a bifunctional methacrylate monomer with a thiodiphenyl sulfide core and thiomethacrylate end groups. The sulfur-rich aromatic structure is why it is reviewed for specialty optical and electronic polymer work, including high-refractive-index resin concepts. Catalog grades commonly list purity >=97% by HPLC. The material is typically described as heat-sensitive; cool, sealed storage is recommended.
Monuo Chemical supplies Bis(4-methacryloylthiophenyl) Sulfide as a specialty chemical raw material with batch identity documentation (COA / SDS). Finished-product claims, labeling and local regulatory filings remain the brand manufacturer’s responsibility. Always confirm grade and assay details against the batch COA for your intended method.

Handling & Use Notes
- Assay/grade check: Confirm HPLC purity and identity on the batch COA before formulation work.
- Handling: Solid at ambient temperature (mp about 64 °C). Use heated mixing or compatible co-solvents when required by your process; dissolve/test in toluene or your target system as needed.
- Storage sensitivity: Heat-sensitive. Keep sealed, cool, and protected from unnecessary heat and light. Supplier literature commonly recommends about 0–10 °C (some listings 2–8 °C). Follow the batch COA/SDS.
- Safety: Follow the SDS for storage, PPE, and waste handling. Public supplier listings may include acute toxicity and irritation related statements—use the batch SDS as the controlling document.
