Frequently asked questions
What is the molar mass of C20H19NO3?
The molar mass of C20H19NO3 is 321.38 g/mol, calculated from standard atomic weights for 20 carbon atoms, 19 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms. The monoisotopic mass is 327.1742 Da.
How many compounds have the formula C20H19NO3?
CompoundList lists 319 compounds with the molecular formula C20H19NO3, including (3,4-Bis(benzyloxy)pyridin-2-yl)methanol, 6-(((1H-Inden-7-yl)oxy)methyl)-4-phenylmorpholin-3-one, 2-[2-(4-Phenoxyphenoxy)propoxy]pyridine. 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 C20H19NO3?
C20H19NO3 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.
