DMSO is a competitive and safer alternative to other polar aprotic solvents and is designed to meet your needs.

Arkema manufactures DMSO in Lacq, France and supplies it worldwide. DMSO is available in drums, totes, isotanks, tank trucks and railcars.

First discovered in 1867, dimethyl sulfoxide is still the most effective aprotic solvent and has many advantages over dimethylformamide and n-methy-2-pyrrolidone. Some of DMSO's characteristics include:

• High polarity and dieletricly constant
• Excellent thermal stability - when heated to 150°C for 24 hours, less than 0.1% assay loss
• Safety - low vapor tension and high flash point
• Toxicity - practically non-toxic
• Recyclable - DMSO can usually be recovered and regenerated efficiently and economically
• Compared to similar solvents, DMSO leads to an increase in reaction rates, higher selectivity and yields, and ability to work at lower temperatures
