Frequently asked questions
What is the molar mass of C18H22N8O?
The molar mass of C18H22N8O is 366.43 g/mol, calculated from standard atomic weights for 18 carbon atoms, 22 hydrogen atoms, 8 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 366.1917 Da.
How many compounds have the formula C18H22N8O?
CompoundList lists 61 compounds with the molecular formula C18H22N8O, including N'-[2-{[(Dimethylamino)methylene]amino}-6-(4-methoxyphenyl)[1,2,4]triazolo[1,5-a]pyrimidin-7-yl]-N,N-dimethyliminoformamide, Syk-IN-1, N-{2-[4-(Azepan-1-yl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]ethyl}pyrazine-2-carboxamide. 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 C18H22N8O?
C18H22N8O 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.
