Fatty alcohols are aliphatic alcohols consisting of a chain of a least six carbon atoms. 1-pentacosanol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 1-pentacosanol can be synthesized from pentacosane. 1-pentacosanol can also be synthesized into 24-methylpentacosan-1-ol. 1-pentacosanol can be found in black elderberry and brussel sprouts, which makes 1-pentacosanol a potential biomarker for the consumption of these food products. 1-Pentacosanol Pentacosyl alcohol C25H52O 368.6798 368.401816286 pentacosan-1-ol pentacosan-1-ol 26040-98-2 CCCCCCCCCCCCCCCCCCCCCCCCCO InChI=1S/C25H52O/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22-23-24-25-26/h26H,2-25H2,1H3 IACKKVBKKNJZGN-UHFFFAOYSA-N belongs to the class of organic compounds known as fatty alcohols.
