Frequently asked questions
What is the molar mass of C25H21NO5?
The molar mass of C25H21NO5 is 415.44 g/mol, calculated from standard atomic weights for 25 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 5 oxygen atoms. The monoisotopic mass is 415.1420 Da.
How many compounds have the formula C25H21NO5?
CompoundList lists 157 compounds with the molecular formula C25H21NO5, including (3S)-2-(((9H-Fluoren-9-yl)methoxy)carbonyl)-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, (3R)-2-{[(9H-Fluoren-9-yl)methoxy]carbonyl}-7-hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, 2-{[4-(2,5-Dimethylbenzyl)-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-6-yl]carbonyl}benzenecarboxylic 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 C25H21NO5?
C25H21NO5 has a degree of unsaturation of 16. 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.
