应用
n-Eicosane is a saturated aliphatic hydrocarbon, which is used to form candles and paraffin waxes with solar energy storage capacity. It is also used in cosmetics, lubricants, plasticizers and in the petrochemical industry. Further, it is useful for special surfactants and in the preparation of certain organic chemicals. In addition to this, it is used as a chromatographic analysis reference material.

备注
Incompatible with strong oxidizing agents.
