The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion. Geosmin is found in corn. 1,10-Dimethyl-9-decalol 11,12,13-Trinor-5-eudesmanol 4,8a-Dimethyloctahydro-4a(2H)-naphthalenol 4,8alpha-Dimethyl-octahydro-naphthalen-4alpha-ol Octahydro-4,8a-dimethyl-4a(2H)-naphthalenol, 9CI C12H22O 182.3025 182.167065326 4,8a-dimethyl-decahydronaphthalen-4a-ol geosmin 19700-21-1 CC1CCCC2(C)CCCCC12O InChI=1S/C12H22O/c1-10-6-5-8-11(2)7-3-4-9-12(10,11)13/h10,13H,3-9H2,1-2H3 JLPUXFOGCDVKGO-UHFFFAOYSA-N belongs to the class of organic compounds known as tertiary alcohols.
