2,3-Dimethylpentane is notable for being one of the two simplest alkanes with optical (enantiomeric) isomerism. The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2.
In 1929 Graham Edgar and George Calingaert made 3,3-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times. [3] For 3,3-dimethylpentane they measured a density of 0.6934 at 20 °C with a rate of change Δd/ΔT of 0.000848.
2,2-Dimethylpentane can form a clathrate hydrate with helper gas molecules. The type of clathrate formed is called "clathrate H". 2,2-Dimethylpentane was the first compound for which the structure was determined. The clathrate has 34 molecules of water per molecule, and also has xenon and hydrogen sulfide as helper molecules.

If one of the methyl groups attached to the third carbon atom were instead an ethyl group, then the name would be 3-ethyl-2,3-dimethylpentane. When there are different alkyl groups, they are listed in alphabetical order.

2-Bromopentane [1] (chiral) 3-Bromopentane; There are four isomers of monobromopentane based on 2-methylbutane: 1-Bromo-2-methylbutane (chiral) 1-Bromo-3-methylbutane; 2-Bromo-2-methylbutane; 2-Bromo-3-methylbutane (chiral) 2,2-Dimethylpropane has only one monobrominated derivative, 1-bromo-2,2-dimethylpropane, also known as neopentyl bromide.
