2-Methylnonane (or isodecane) makes a significant portion of fuels like petrol as a fuel additive, making it essential for energy production.^[1] It is useful for various applications in organic chemistry as it easily dissolves in non-polar solvents such as hexane and benzene.^[1]

Its physical state is liquid and appears colorless. It smells of petroleum distillates. May be fatal if swallowed and enters airways. It is a category 3 flammable liquid and has a category 1 aspiration toxicity. 2-Methylnonane is insoluble and floats on water and evaporates slowly.^[2]

2-Methylnonane is achiral as it lacks a chiral center; that is, it is an asymmetrical molecule and it cannot be superimposed on its mirror image. It represents the first among the four monomethyl nonane isomers.^[3]^[4]^[5]
