How many compounds have the formula C16H20N4O?
CompoundList lists 279 compounds with the molecular formula C16H20N4O, including N-{[5-(1-Methyl-1H-pyrazol-4-yl)pyridin-3-yl]methyl}cyclopentanecarboxamide, 1-(3-(1H-1,2,3-Triazol-1-yl)pyrrolidin-1-yl)-3-(o-tolyl)propan-1-one, 1-(4-(2H-1,2,3-Triazol-2-yl)piperidin-1-yl)-2-(m-tolyl)ethanone. Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of C16H20N4O?
C16H20N4O has a degree of unsaturation of 9. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
