Frequently asked questions
What is the molar mass of C18H20ClN3O?
The molar mass of C18H20ClN3O is 329.83 g/mol, calculated from standard atomic weights for 18 carbon atoms, 20 hydrogen atoms, 1 chlorine atom, 3 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 332.1483 Da.
How many compounds have the formula C18H20ClN3O?
CompoundList lists 110 compounds with the molecular formula C18H20ClN3O, including Ondansetron hydrochloride, 4-Benzyl-N-(3-chlorophenyl)-1-piperazinecarboxamide, Fabesetron hydrochloride. 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 C18H20ClN3O?
C18H20ClN3O 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.
