Frequently asked questions
What is the molar mass of C21H23NO3?
The molar mass of C21H23NO3 is 337.42 g/mol, calculated from standard atomic weights for 21 carbon atoms, 23 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms. The monoisotopic mass is 343.2055 Da.
How many compounds have the formula C21H23NO3?
CompoundList lists 357 compounds with the molecular formula C21H23NO3, including Methyl 4-[3-(2-tert-butylanilino)-3-oxoprop-1-en-1-yl]benzoate, (9H-Fluoren-9-yl)methyl 4-hydroxy-4-methylpiperidine-1-carboxylate, 4-(4-Vinylphenoxy)-piperidine-1-carboxylic acid benzyl 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 C21H23NO3?
C21H23NO3 has a degree of unsaturation of 11. 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.
