Application

2-Pentanol is a secondary alcohol that can be used as:
  • A hydrogen donor in the synthesis of methyl furan via catalytic transfer hydrogenation of furfural over a ruthenium/ruthenium oxide/carbon catalyst.
  • A reagent in one-pot synthesis of brominated derivatives of 1,3-dioxolane.
  • A solvent for the synthesis of organic molecules such as 2, 4-diaminopyrimidines and 4-aza-podophyllotoxins.
