Frequently asked questions
What is the molar mass of C19H20N4O?
The molar mass of C19H20N4O is 320.40 g/mol, calculated from standard atomic weights for 19 carbon atoms, 20 hydrogen atoms, 4 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 320.1637 Da.
How many compounds have the formula C19H20N4O?
CompoundList lists 238 compounds with the molecular formula C19H20N4O, including Niraparib, 2-(4-(Piperidin-3-yl)phenyl)-2H-indazole-7-carboxamide, AG-14361. 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 C19H20N4O?
C19H20N4O 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.
