Frequently asked questions
What is the molar mass of C18H21ClN4O2S?
The molar mass of C18H21ClN4O2S is 392.90 g/mol, calculated from standard atomic weights for 18 carbon atoms, 21 hydrogen atoms, 1 chlorine atom, 4 nitrogen atoms, 2 oxygen atoms and 1 sulfur atom. The monoisotopic mass is 392.1074 Da.
How many compounds have the formula C18H21ClN4O2S?
CompoundList lists 63 compounds with the molecular formula C18H21ClN4O2S, including 8-[(4-Chlorophenyl)methylsulfanyl]-3-methyl-7-(3-methylbutyl)purine-2,6-dione, N-(4-Chloro-2,5-dimethoxyphenyl)-4-pyridin-2-ylpiperazine-1-carbothioamide, 5-((4-Chlorophenyl)(2,6-dimethylmorpholino)methyl)-2-methylthiazolo[3,2-b][1,2,4]triazol-6-ol. 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 C18H21ClN4O2S?
C18H21ClN4O2S 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.
