Application

Levulinic acid is a precursor for the synthesis of useful intermediates such as γ-valerolactone, ethyl levulinate, pentanoic acid and 2-methyl-tetrahydrofuran.[1][2][3] Derivatization and esterification of levulinic acid results in potential biofuels.[4][5]

It can also be used in:
  • The preparation of catalytic composite to synthesize 5-hydroxymethylfurfural and furfural.[6]
  • The synthesis of a commercial fragrance, fraistone.[7]
  • The synthesis of pyrrolidone derivatives via reductive amination.[8]
  • The total synthesis of mycobacterial arabinogalactan.[9]
