Frequently asked questions
What is the molar mass of C7H8N4O?
The molar mass of C7H8N4O is 164.17 g/mol, calculated from standard atomic weights for 7 carbon atoms, 8 hydrogen atoms, 4 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 164.0698 Da.
How many compounds have the formula C7H8N4O?
CompoundList lists 344 compounds with the molecular formula C7H8N4O, including 6-Ethoxypurine, 1,3-Dihydro-5,6-diamino-2H-benzimidazol-2-one, 3-Hydroxy-5,6-dimethyl-1H-pyrazolo-(3,4B)-pyrazine. 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 C7H8N4O?
C7H8N4O 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.
