Frequently asked questions
What is the molar mass of C12H21N3?
The molar mass of C12H21N3 is 207.32 g/mol, calculated from standard atomic weights for 12 carbon atoms, 21 hydrogen atoms and 3 nitrogen atoms. The monoisotopic mass is 207.1735 Da.
How many compounds have the formula C12H21N3?
CompoundList lists 736 compounds with the molecular formula C12H21N3, including 3-{[1-(Propan-2-yl)-1H-pyrazol-5-yl]methyl}piperidine, 4-[2-(1-Ethyl-1H-pyrazol-4-yl)ethyl]piperidine, 1-tert-Butyl-4-[(pyrrolidin-2-yl)methyl]-1H-pyrazole. 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 C12H21N3?
C12H21N3 has a degree of unsaturation of 4. 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.
