Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Isobutylidene is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Isobutylidene can be found in wild celery, which makes isobutylidene a potential biomarker for the consumption of this food product. 1,1-Diureidisobutane 1,1'-Isobutylidenebisurea 4,4'-(2-Methylpropylidene)bisphenol 4,4'-isobutylidenediphenol Diureidoisobutane IBDU Isobutyldiurea Isobutylenediurea Isobutylidene diurea Isobutylidenediurea Isodur N,N''-(2-methylpropane-1,1-diyl)diurea N,N''-(2-Methylpropylidene)bisurea N,n''-(isobutylidene)diurea Urea, 1,1'-isobutylidenedi- Urea, N,N''-(2-methylpropylidene)bis- C6H14N4O2 174.201 174.111675712 [1-(carbamoylamino)-2-methylpropyl]urea 1-(carbamoylamino)-2-methylpropylurea CC(C)C(NC(N)=O)NC(N)=O InChI=1S/C6H14N4O2/c1-3(2)4(9-5(7)11)10-6(8)12/h3-4H,1-2H3,(H3,7,9,11)(H3,8,10,12) QFHMNFAUXJAINK-UHFFFAOYSA-N belongs to the class of organic compounds known as ureas.
