Frequently asked questions
What is the molar mass of C20H21NO4S?
The molar mass of C20H21NO4S is 371.45 g/mol, calculated from standard atomic weights for 20 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom, 4 oxygen atoms and 1 sulfur atom. The monoisotopic mass is 377.1329 Da.
How many compounds have the formula C20H21NO4S?
CompoundList lists 122 compounds with the molecular formula C20H21NO4S, including Gsk2801, N-[(9H-Fluoren-9-ylmethoxy)carbonyl]-L-methionine, (2R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(methylsulfanyl)butanoic acid. 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 C20H21NO4S?
C20H21NO4S has a degree of unsaturation of 11. 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.
