Frequently asked questions
What is the molar mass of C21H25NO4S?
The molar mass of C21H25NO4S is 387.49 g/mol, calculated from standard atomic weights for 21 carbon atoms, 25 hydrogen atoms, 1 nitrogen atom, 4 oxygen atoms and 1 sulfur atom. The monoisotopic mass is 387.1504 Da.
How many compounds have the formula C21H25NO4S?
CompoundList lists 94 compounds with the molecular formula C21H25NO4S, including Isopropyl 4-(4-ethylphenyl)-2-[(tetrahydro-2-furanylcarbonyl)amino]-3-thiophenecarboxylate, Thiodemecolcine, N-Benzyl-N-(1,1-dioxidotetrahydrothiophen-3-yl)-2-(4-ethylphenoxy)acetamide. 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 C21H25NO4S?
C21H25NO4S 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.
