Frequently asked questions
What is the molar mass of C21H25NO3?
The molar mass of C21H25NO3 is 339.44 g/mol, calculated from standard atomic weights for 21 carbon atoms, 25 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms. The monoisotopic mass is 339.1834 Da.
How many compounds have the formula C21H25NO3?
CompoundList lists 309 compounds with the molecular formula C21H25NO3, including 4-{(E)-[(4-Butoxyphenyl)methylidene]amino}phenyl butanoate, Propyl 2-[(2,6-diethylphenyl)carbamoyl]benzoate, 6-[(4-tert-Butylphenoxy)methyl]-4-phenylmorpholin-2-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 C21H25NO3?
C21H25NO3 has a degree of unsaturation of 10. 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.
