Dimethylsulfoxide (DMSO)
DMSO is a clear, transparent liquid. DMSO is high polar and high boiling solvent completely miscible with water. It has a low toxicity profile compared to the majority of competing solvents (like n-methyl pyrrolidone, NMP).
DMSO is used as solvent both in synthesis and formulation in many different applications: pharmaceuticals intermediate, agrochemicals, polymers, refineries, electronics, antifreeze, fibres and extraction.
Connect Chemicals offer high purity grades for industrial markets, pharmaceuticals and electronics.
Recently DMSO have be widely used in NMP replacement thanks to similar miscibility, safe handling and solubility, but improved solvency, stability and acute toxicity profile

DMSO is also occurring in nature as part of the natural sulphur cycle, instead NMP is not occurring in nature.
