description Product Description
Dimethyl sulfoxide is widely used as a solvent in chemical reactions due to its ability to dissolve a broad range of organic and inorganic compounds. It is particularly valuable in pharmaceutical manufacturing for enhancing the penetration of drugs through biological membranes, making it useful in topical formulations. In cryobiology, it serves as a cryoprotectant to preserve cells, tissues, and organs at low temperatures. Additionally, it is employed in the synthesis of polymers and as a reaction medium in organic synthesis. Its anti-inflammatory and analgesic properties also make it a component in certain medical treatments.
