Chemical compound
5-Methylfurfuryl alcohol is an organic compound with the formula C6 H8 O2 . It is one of many volatile compounds present in Nicotiana tabacum ,[ 3] and is formed from the reduction of 5-methylfurfural ,[ 4] a compound formed from the reduction of 5-bromo- or 5-chloromethylfurfural .[ 5] It is a colorless liquid listed as a food additive with FEMA number 4544 and JECFA number 2099.[ 2]
Occurrence
5-Methylfurfuryl alcohol naturally occurs as one of many volatile compounds present in Nicotiana tabacum , or cultivated tobacco. The compound appears at much lower concentration in tobacco leaves than the more common aldehyde furfural .[ 3]
As the reduction product of 5-methylfurfural, 5-methylfurfuryl alcohol occurs in barrel-aged wines along with 5-methylfurfuryl ethyl ether.[ 4]
Synthesis
5-Methylfurfuryl alcohol can be produced through a reduction of 5-methylfurfural with lithium aluminium hydride ,[ 4] though historically the reduction has been performed starting with methyl 5-methyl–2-furoate rather than 5-methylfurfural.[ 6]
