Uses

2,5-dimethyl-2,4-hexadiene is a volatile alkyl compound present in tobacco smoke. It is used as a potential biomarker in breath for prediction of lung cancer.

Purification Methods

Distil, then repeatedly fractionally crystallise it by partial freezing. Immediately before use, the diene is passed through a column containing Woelm silica gel (activity I) and Woelm alumina (neutral) in separate layers. [Beilstein 1 IV 1043.]
