Patent: US20160082162 A1 | Dirito, Jenna et al. published a patent in 2016| cas: 550-33-4

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4) belongs to tetrahydrofuran derivatives.Tetrahydrofuran has many industry uses as a solvent including in natural and synthetic resins, high polymers, fat oils, rubber, polymer. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Synthetic Route of C10H12N4O4
