What is Dimethyl Sulfone?
Dimethyl sulfone (CAS 67-71-0), also widely recognized in commercial supply chains as methyl sulfonyl methane (MSM), is an exceptionally stable organosulfur compound featuring the chemical formula (CH₃)₂SO₂.
Appearing as an odorless, bright white crystalline powder, this versatile material possesses a melting point of 107–110°C and a high boiling point of 238°C. Due to its outstanding thermal stability, strong polarity, and non-corrosive chemical nature, high purity dimethyl sulfone serves as a critical organic synthesis intermediate, a specialized high temperature reaction solvent, and an essential raw material in advanced chemical manufacturing.
In industrial chemical synthesis, dimethyl sulfone CAS 67-71-0 acts as a polar, high-boiling reaction medium ideal for nucleophilic substitutions, polymer synthesis, and complex organic transformations where conventional solvents volatilize or decompose.
Furthermore, as a key fine chemical intermediate, it plays a strategic role in the formulation of specialized coatings, synthetic resins, agricultural chemicals, and performance additives. Modern industrial sectors rely heavily on bulk organic sulfur powder to optimize reaction yields and maintain thermal control during multi-step organic reactions.

SuperiorDimethyl Sulfone Series | Reliable Quality & Sufficient Supply
At Zhishang Bio, we operate state-of-the-art, continuous-flow synthesis infrastructure specifically engineered for industrial scale chemical production. Utilizing advanced liquid-phase oxidation technology followed by precision multi-stage recrystallization, our continuous production process yields a guaranteed assay purity of ≥99.9%.
By employing automated analytical testing—including Gas Chromatography (GC), High-Performance Liquid Chromatography (HPLC), and Karl Fischer moisture analysis—our dedicated QC team ensures ultra-low moisture content (≤0.2%) and negligible heavy metal residues. This rigorous quality management system guarantees that every batch meets international standards for demanding industrial applications.
To satisfy dynamic global market demands, our production facility maintains a robust manufacturing capacity of over 5,000 metric tons per year. Supported by a modern 3,000 m² temperature-controlled warehousing hub, we maintain a constant standing inventory of over 200 metric tons of ready-to-ship Dimethyl Sulfone.
Our flexible manufacturing setup accommodates diverse client specifications, offering standard 25 kg fiber drums with double PE inner liners, 500 kg super sacks, or custom tailored bulk packaging designed for automated industrial charging systems.
FAQ
Our standard export packaging consists of 25 kg fiber drums equipped with double‑layer moisture‑proof polyethylene bags, as well as 500 kg jumbo bags for bulk industrial use. Dimethyl sulfone is hydroscopic, so it should be stored in a cool, dry, well‑ventilated warehouse away from direct sunlight, strong oxidizers, and open flames. Kept in unopened original containers under ambient conditions, it maintains a shelf life of 24 months.
Yes. We offer fully customizable particle sizes ranging from standard 20‑40 mesh granules down to ultra‑fine 80‑100 mesh micronized powders. Our flexible milling and sifting technology enables us to tailor particle size distribution to your specific formulation requirement, ensuring optimal dissolution rates and seamless blending.
Every batch of CAS 67‑71‑0 dimethyl sulfone undergoes strict analytical verification prior to warehouse clearance. We provide a comprehensive Certificate of Analysis (CoA) with each shipment, detailing GC purity, melting point range, heavy metals (Pb, As), loss on drying, and residue on ignition. Retained samples are kept for 2 years for full traceability.
What compliance documentation and trade terms (Incoterms) do you support for international shipping?
We support standard global trade terms including FOB, CFR, CIF, DDP, and DAP. Complete regulatory and shipping documentation packages —including SDS (GHS compliant), Certificate of Origin (COO), REACH compliance statements, ISO9001 certifications, and bill of lading support—are provided to ensure smooth customs clearance worldwide.
