Frequently asked questions
What is the molar mass of C20H23NO4S?
The molar mass of C20H23NO4S is 373.47 g/mol, calculated from standard atomic weights for 20 carbon atoms, 23 hydrogen atoms, 1 nitrogen atom, 4 oxygen atoms and 1 sulfur atom. The monoisotopic mass is 373.1348 Da.
How many compounds have the formula C20H23NO4S?
CompoundList lists 108 compounds with the molecular formula C20H23NO4S, including Colchicine, N-deacetyl-10-thio-, 3-[2-(3,4-Dimethoxyphenyl)ethyl]-2-(4-methoxyphenyl)-1,3-thiazolidin-4-one, Ethyl 5,5-dimethyl-2-[(2-methylbenzoyl)amino]-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylate. 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 C20H23NO4S?
C20H23NO4S 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.
