Frequently asked questions
What is the molar mass of C18H25NO3?
The molar mass of C18H25NO3 is 303.40 g/mol, calculated from standard atomic weights for 18 carbon atoms, 25 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms. The monoisotopic mass is 308.2148 Da.
How many compounds have the formula C18H25NO3?
CompoundList lists 282 compounds with the molecular formula C18H25NO3, including rac-Methyl (3R,4R)-1-benzyl-4-(oxan-4-yl)pyrrolidine-3-carboxylate, N-[2-(1-Cyclohexen-1-yl)ethyl]-4-(2-methoxyethoxy)benzamide, 4-(Benzylamino)-2-hydroxybicyclo[2.2.2]octane-1-carboxylic acid ethyl ester. 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 C18H25NO3?
C18H25NO3 has a degree of unsaturation of 7. 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.
