Used primarily as a solvent in laboratories and in the formulation of fuels due to its flammable nature. It serves as a component in gasoline to help regulate combustion properties. Also used in research settings as a standard in chromatography and for calibration in analytical testing. Its high purity grades are utilized in environmental testing to detect pollutants in air and water samples. Additionally, decane finds use in some industrial cleaning processes and as a reference compound in engine performance studies.
