Common Nameindole-3-glycol aldehyde
DescriptionIndole-3-glycol aldehyde, also known as 2-hydroxy-2-(1h-indol-3-yl)acetaldehyde, is a member of the class of compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Indole-3-glycol aldehyde is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Indole-3-glycol aldehyde can be found in a number of food items such as tree fern, jostaberry, pitanga, and pine nut, which makes indole-3-glycol aldehyde a potential biomarker for the consumption of these food products.
