Frequently asked questions
What is the molar mass of C8H9N3O?
The molar mass of C8H9N3O is 163.18 g/mol, calculated from standard atomic weights for 8 carbon atoms, 9 hydrogen atoms, 3 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 171.1248 Da.
How many compounds have the formula C8H9N3O?
CompoundList lists 678 compounds with the molecular formula C8H9N3O, including 2-(Pyrrolo[2,1-f][1,2,4]triazin-5-yl)ethan-1-ol, 5-(5-Methylfuran-2-yl)-1H-pyrazol-4-amine, 3-Methoxy-1H-indazol-4-amine. 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 C8H9N3O?
C8H9N3O has a degree of unsaturation of 6. 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.
