Frequently asked questions
What is the molar mass of C12H21NO2?
The molar mass of C12H21NO2 is 211.31 g/mol, calculated from standard atomic weights for 12 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 2 oxygen atoms. The monoisotopic mass is 211.1572 Da.
How many compounds have the formula C12H21NO2?
CompoundList lists 1,029 compounds with the molecular formula C12H21NO2, including rac-Ethyl (1R,2R)-2-[(piperidin-4-yl)methyl]cyclopropane-1-carboxylate, tert-Butyl N-(1-cyclopropylprop-2-en-1-yl)-N-methylcarbamate, tert-Butyl N-[(1-ethenylcyclobutyl)methyl]carbamate. 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 C12H21NO2?
C12H21NO2 has a degree of unsaturation of 3. 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.
