Frequently asked questions
What is the molar mass of C21H21NO5?
The molar mass of C21H21NO5 is 367.40 g/mol, calculated from standard atomic weights for 21 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 5 oxygen atoms. The monoisotopic mass is 370.1608 Da.
How many compounds have the formula C21H21NO5?
CompoundList lists 333 compounds with the molecular formula C21H21NO5, including Corynoline, (S)-Allyl 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-hydroxypropanoate, Fmoc-4-amino-tetrahydropyran-4-carboxylic 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 C21H21NO5?
C21H21NO5 has a degree of unsaturation of 12. 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.
