[1] 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.
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.
A method to produce 3,3-dimethylpentane is to react tert-amyl chloride (CH 3 CH 2 (CH 3)C 2 Cl) with propionaldehyde producing 3,3-dimethylpentan-2-ol. This is then dehydrated to produce 3,3-dimethylpent-2-ene, which when hydrogenated produces some 3,3-dimethylpentane, but also 2,3-dimethylpentane. [2]
2,3-Dimethyl-1-butene is an organic compound with the formula CH 2 =C(CH 3)CH(CH 3) 2. Like the other isomers of dimethylbutene, it is a colorless liquid. Together with 2,3-dimethyl-2-butene it can be produced by dimerization of propylene. It is a precursor to the commercial fragrance tonalide. [1]
2,3,3-Trimethylpentane is a chemical compound in the family of hydrocarbons which has a formula of C 8 H 18. It is an isomer of octane . It has a role as a human metabolite, a bacterial metabolite and a mammalian metabolite. [ 2 ]
It can be prepared by base-catalyzed isomerization of 2,3-dimethyl-1-butene. [2] Another route involves direct dimerization of propylene. [3] It can also be produced by photolysis of tetramethylcyclobutane-1,3-dione. [4]

4-Methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP) is a metabolite of bisphenol A (BPA). [1] MBP has potent estrogenic activity in vitro and in vivo , up to thousandfold stronger than BPA. [ 2 ] It may also play a role in neuronal cell apoptosis [ 3 ] and may increase risk for several forms of cancer.
