Regulatory and process considerations for switching to dimethyl sulfoxide Dimethyl sulfoxide (DMSO, CAS 67-68-5) is a highly polar, water-miscible dipolar aprotic solvent with a relatively high boiling point (189 °C) and low…
Regulatory and process considerations for switching to dimethyl sulfoxide Dimethyl sulfoxide (DMSO, CAS 67-68-5) is a highly polar, water-miscible dipolar aprotic solvent with a relatively high boiling point (189 °C) and low acute toxicity. As EU regulation tightens around the nitrogen-containing solvents N-methyl-2-pyrrolidone (NMP) and N,N-dimethylformamide (DMF), manufacturers in battery, polymer, and pharmaceutical processing are … Read more
