Dimethyl sulfoxide (DMSO) is widely used as a solvent in various chemical reactions due to its ability to dissolve a broad range of organic and inorganic compounds. It is particularly valuable in pharmaceutical research for enhancing the penetration of drugs through biological membranes, making it a key component in transdermal drug delivery systems. In the medical field, DMSO is applied topically to reduce inflammation and pain, especially in conditions like arthritis and interstitial cystitis. It is also utilized in cryopreservation to protect cells and tissues during freezing and thawing processes. Additionally, DMSO serves as a reagent in organic synthesis, facilitating reactions such as oxidation and reduction. Its role in industrial applications includes use as a paint stripper and in the production of microelectronics.
