Polar aprotic solvents are a unique class of high-polarity solvents that do not donate hydrogen atoms (protons) via hydrogen bonding. Characterized by their strong dipole moments and ability to dissolve a wide range of ionic and non-ionic compounds, these solvents play an indispensable role in organic synthesis, pharmaceutical manufacturing, polymer processing, and electronics production.
Our Best-Selling Dipolar Aprotic Products




Dimethyl Sulfoxide(DMSO)
Dimethyl sulfoxide (DMSO) is an extremely important universal solvent that is soluble in both water and organic solvents. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
Dimethylacetamide (DMAC)
N,N−Dimethylacetamide (DMAc) is a dipolar, aprotic, high-boiling, oily solvent and reagent. It is miscible with water and most oxygen- and nitrogen-containing organic solvents. It has a faint ammonia odor.
N,N-DimethyIformamide(DMF)
N,N-Dimethylformamide (DMF) is an excellent polar solvent for various classes of compounds, the dissolution being favoured by interactions of the substrate with DMF.
Glycerol
Glycerol is a simple triol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in lipids known as glycerides. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
