HMF is an organic compound derived from plant-based sugars (i.e. glucose & fructose). As a platform chemical, it can be processed into various biochemicals that are currently still derived from fossil fuels. HMF is highly water soluble and can be processed into diesel-like liquid biofuels ("furanic biofuels"). These are in some ways superior to ethanol. For example, compared to ethanol, 2,5-dimethylfuran (DMF) has a higher energy density, has a higher boiling point (by 20°C), and is not soluble in water. DMF is similar to gasoline and is compatible with the existing liquid transportation fuel infrastructure, having already been used as a gasoline additive.
