Dimethyl Sulfoxide (DMSO), with the CAS No. 67-68-5, is a versatile organosulfur compound known as the "universal solvent" due to its exceptional ability. Key applications include acting as a solvent for reactions, a prescription medication for bladder conditions, a solvent in pharmaceuticals, and as an industrial cleaning agent.
What is Dimethyl Sulfoxide/DMSO?
DMSO, or dimethyl sulfoxide, is a by-product of paper making. It comes from a substance found in wood. DMSO (CAS 67-68-5) has been used as an industrial solvent since the mid-1800s. From about the mid-20th century, researchers have explored its use as an anti-inflammatory agent.
