5-Methyl furfural Siv Thiab Synthesis

Chemical Properties	5-Methylfurfural muaj qab zib, ntsim, sov tsw nrog qab zib zoo li caramel tsw. Tej zaum yuav tau npaj los ntawm sucrose nrog HCL, tom qab ntawd kho nrog stannous chloride; los ntawm ntau yam methylpentoses los ntawm distillation nrog acid.
Lub cev muaj zog	colorless rau lub teeb daj kua. Soluble nyob rau hauv benzene, toluene, carbon tetrachloride thiab lwm yam kuab tshuaj, insoluble nyob rau hauv dej.
Qhov tshwm sim	Tshaj tawm pom muaj nyob rau hauv qaub cherry, kua txiv kab ntxwv, cranberry, blueberry, guava, txiv hmab txiv ntoo, raisin, txiv duaj, txiv duaj dub, strawberry jam, asparagus, zaub ntug hauv paus, dos, qos yaj ywm, tswb kua txob, txiv lws suav, cinnamon, bark, clove bud, qhob cij parmesan cheese, yogurt, butter, qe, ntses rog, nqaij nyuj, nqaij npuas daim siab, npias, cognac, kas fes, tshuaj yej, barley, filberts, paj kws, txiv laum huab xeeb, oats, taum mog, ci txiv maj phaub, cloudberry, passion txiv hmab txiv ntoo, pecan, nceb, Starfruit, trassi, sesame noob, mango, tamarind, nplej bran, quince, qos yaj ywm qab zib, sukiyaki, calamus, licorice, malt, wort, elderberry, mangosteen, kiwifruit, buchu roj, Bourbon vanilla, qus nplej, chicory paus, cw, oyster , clam, okra, pistachio txiv ntseej thiab maté
Siv	5-Methyl-2-furaldehyde yog siv los ua cov tshuaj tsw qab. Nws yog siv cov pa luam yeeb nrog cov essence.
Siv	5-methylfurfural yog ib qho nruab nrab rau kev sib txuas ntawm s-bioallethrin thiab prallethrin.Nws yog siv rau kev sib xyaw kas fes, chocolate, txiv ntseej, caramel, txuj lom thiab khoom qab zib. Siv nyob rau hauv lub synthesis ntawm kws tshuaj intermediates.
Kev npaj	Los ntawm sucrose nrog HCl, tom qab ntawd kho nrog stannous chloride; 5-Methyl furfural yog tsim los ntawm distillation ntawm ntau yam methylpentoses nrog acid ua ke.
Txhais	ChEBI: 5-methyl-2-furaldehyde yog ib tug tswv cuab ntawm furans thiab aldehyde. Nws muaj lub luag haujlwm ua Maillard cov khoom siv tshuaj tiv thaiv, tib neeg metabolite, EC 2.2.1.6 (acetolactate synthase) inhibitor thiab tus neeg sawv cev flavoring.
