Dodecane (also known as dihexyl, bihexyl, adakane 12, or duodecane) is an oily liquid n-alkane hydrocarbon with the chemical formula C₁₂H₂₆ (which has 355 isomers).

It is used as a solvent, distillation chaser, and scintillator component. It is used as a diluent for tributyl phosphate (TBP) in nuclear reprocessing plants.{{cite book|last=Rydberg|first=Jan|title=Solvent Extraction Principles and Practice|year=2004|publisher=Marcel Dekker|isbn=0-8247-5063-2|page=524}}
