Frequently asked questions
What is the molar mass of C20H18N4O?
The molar mass of C20H18N4O is 330.39 g/mol, calculated from standard atomic weights for 20 carbon atoms, 18 hydrogen atoms, 4 nitrogen atoms and 1 oxygen atom. The monoisotopic mass is 330.1481 Da.
How many compounds have the formula C20H18N4O?
CompoundList lists 126 compounds with the molecular formula C20H18N4O, including Pki-166, 2-Ethyl-1-[(2-furylmethyl)amino]-3-methylpyrido[1,2-a]benzimidazole-4-carbonitrile, 4-(4-Phenylpiperazin-1-yl)-[1]benzofuro[3,2-d]pyrimidine. 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 C20H18N4O?
C20H18N4O has a degree of unsaturation of 14. 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.
