How many compounds have the formula C18H18N4OS?
CompoundList lists 179 compounds with the molecular formula C18H18N4OS, including N-((2-Methyl-2,4,5,6-tetrahydrocyclopenta[c]pyrazol-3-yl)methyl)-2-phenylthiazole-4-carboxamide, (4-(2H-1,2,3-Triazol-2-yl)piperidin-1-yl)(4-(thiophen-3-yl)phenyl)methanone, 2-({1-[4-(Thiophen-3-yl)benzoyl]pyrrolidin-2-yl}methyl)-2H-1,2,3-triazole. 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 C18H18N4OS?
C18H18N4OS has a degree of unsaturation of 12. 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.
