intermediate, e.g. to 3,4-dihydropyran. It is prepared by hydrogenation of furfural. It is a precursor to 1,5-pentanediol. THFA is often used in epoxy resin...

polysaccharide and oligosaccharide ketoses yields simpler sugars followed by furfural. The dehydrated ketose then reacts with two equivalents of resorcinol in...

The most important tests for pentoses rely on converting the pentose to furfural, which then reacts with a chromophore. In Tollens’ test for pentoses (not...
