Frequently asked questions
What is the molar mass of C9H13NO?
The molar mass of C9H13NO is 151.21 g/mol, calculated from standard atomic weights for 9 carbon atoms, 13 hydrogen atoms, 1 nitrogen atom and 1 oxygen atom. The monoisotopic mass is 156.1311 Da.
How many compounds have the formula C9H13NO?
CompoundList lists 1,404 compounds with the molecular formula C9H13NO, including 1-[(2S)-Piperidin-2-yl]but-3-yn-1-one, 1-[(3R)-Pyrrolidin-3-yl]pent-4-yn-1-one, 1-[(3S)-Pyrrolidin-3-yl]pent-3-yn-1-one. 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 C9H13NO?
C9H13NO has a degree of unsaturation of 4. 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.
