Dimethyl Sulfoxide DMSO CAS 67-68-5 is a polar aprotic solvent and process material supplied by Suzhou Pharmaceutical Technology Co., Ltd. for B2B procurement, sample evaluation, and specification-driven export supply. We provide COA and MSDS for all shipments, COO for pallet quantities and commercial export orders, and documentation review for buyers in South America, Australia, New Zealand, Mexico, and Canada.

> Product Overview
DMSO is identified by PubChem CID 679 with molecular formula C2H6OS, molecular weight 78.14, InChIKey IAZDPXIOMUYVGZ-UHFFFAOYSA-N, and SMILES CS(=O)C. Common aliases include dimethyl sulphoxide, methyl sulfoxide, methylsulfinylmethane, dimethylsulfoxide, dimethyl sulfur oxide, and sulfinylbis(methane).
> Applications and Technical Reference
DMSO is evaluated as a polar aprotic solvent, process solvent, extraction or cleaning solvent, and formulation research material where its miscibility profile and solvating behavior are relevant. Final use, quality grade, residual-solvent controls, safety handling, and regulatory classification must be confirmed by the buyer for the destination market. Technical citation: PubChem CID 679, accessed in 2026, lists Dimethyl Sulfoxide CAS 67-68-5 with formula C2H6OS, molecular weight 78.14, InChIKey IAZDPXIOMUYVGZ-UHFFFAOYSA-N, and n=247 synonyms.
