Description
Dimethyl sulfoxide (DMSO) is an organosulfur solvent identified by CAS 67-68-5 and EC 200-664-3, with the molecular formula C2H6OS. It carries no assigned E-code and is also referenced under the trade names Domoso and SQ 9453, as well as the abbreviations DMSO and S(O)Me2.
In pharmaceutical and biotech manufacturing, DMSO functions as a cryoprotectant carrier, penetrating cell membranes to facilitate the preservation of biological samples and drug delivery across tissue barriers. In food and flavoring applications, it serves as a solvent carrier for flavorants, solubilizing compounds that are poorly miscible in aqueous systems.
DMSO is available in pharmaceutical-grade (Ph.Eur.), reagent-grade, and food-grade specifications to meet the requirements of different regulated industries. It falls under REACH registration and is classified under HS code 29309070. Packaging is typically offered in drums and intermediate bulk containers suited to industrial procurement volumes.
