Frequently asked questions
What is the molar mass of C21H18N6O?
The molar mass of C21H18N6O is 370.42 g/mol, calculated from standard atomic weights for 21 carbon atoms, 18 hydrogen atoms, 6 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 370.1542 Da.
How many compounds have the formula C21H18N6O?
CompoundList lists 55 compounds with the molecular formula C21H18N6O, including 2-((3-Pyridinylmethyl)amino)-3-((E)-(((E)-3-pyridinylmethyl)imino)methyl)-4H-pyrido(1,2-A)pyrimidin-4-one, 2,6-Bis(4-azidobenzylidene)-4-methylcyclohexan-1-one, 6H-Dipyrido(3,2-b:2',3'-e)(1,4)diazepin-6-one, 11-ethyl-5,11-dihydro-5-methyl-2-(1H-pyrrolo(3,2-b)pyridin-3-yl)-. 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 C21H18N6O?
C21H18N6O has a degree of unsaturation of 16. 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.
