3,4{3}}Dihydro{5}}2H-pyran (DHP, CAS 110{9}}87-2) lu ndoxe la bu amul melo, dafay tàkk, am xet gu woyof gu niru ak ether, te dafay nekk diggante bu am solo ci synthese organik. Bimu nekkee ether heterocyclic bu am 6 cër, DHP ñu ngi ko gëna xamee ci liggéeyam ci aar alkol ci forme ether tetrahydropyranyl (THP). Loolu moo tax mënul ñàkk ci synthese yu bari ci ay produit farmasi, ay produit nature ak ay produit chimik yu yam.
DHP ñu ngi koy defaree ci hydrogenation katalitik bu dihydropyran wala furfural bu bawoo ci biomass, mu méngoo bu baax ak bëgg-bëggu chimie buy yàgg. Màndargaam yu am solo yi -dañuy dëgër ci base, sensitivite ci asid, ak volatilite- jàppale nañu ko itam ci resin, coating, ak defar ay produit chimik yu baax.
