General Description

5-Methylfurfural is formed during the photoexposition of ranitidine hydrochloride. It is employed as potential age marker for Madeira wine. It is a volatile compound present in Lavandula stoechas, Lavandula angustifolia and Lavandula angustifolia x latifolia unifloral honeys.

Metabolic pathway

The biotransformation of 5-methyl-2-furaldehyde is the conversion to 5-methylfuroylgycine and 5-methyl-2- furylmethylketone by rats.
