Frequently asked questions
What is the molar mass of C18H20ClN3O2?
The molar mass of C18H20ClN3O2 is 345.83 g/mol, calculated from standard atomic weights for 18 carbon atoms, 20 hydrogen atoms, 1 chlorine atom, 3 nitrogen atoms and 2 oxygen atoms. The monoisotopic mass is 345.1244 Da.
How many compounds have the formula C18H20ClN3O2?
CompoundList lists 157 compounds with the molecular formula C18H20ClN3O2, including N-(4-Chlorophenethyl)-2-(3-oxo-3,5,6,7-tetrahydro-2H-cyclopenta[c]pyridazin-2-yl)propanamide, 3-(3-Chlorophenyl)-N-(2-(3-oxo-3,5,6,7-tetrahydro-2H-cyclopenta[c]pyridazin-2-yl)ethyl)propanamide, (2R)-1-[4-(2-Chloropyrimidin-4-yl)piperidin-1-yl]-2-methoxy-2-phenylethanone. 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 C18H20ClN3O2?
C18H20ClN3O2 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.
