Frequently asked questions
What is the molar mass of C23H21NO4?
The molar mass of C23H21NO4 is 375.42 g/mol, calculated from standard atomic weights for 23 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 4 oxygen atoms. The monoisotopic mass is 375.1471 Da.
How many compounds have the formula C23H21NO4?
CompoundList lists 163 compounds with the molecular formula C23H21NO4, including N-(9H-Fluoren-2-yl)-3,4,5-trimethoxybenzamide, 4-((2-(1,1'-Biphenyl)-4-yl-1-ethoxy-2-oxoethyl)amino)benzoic acid, 4-[(3,4-Dimethoxyphenyl)methylidene]-1,2,3,4-tetrahydroacridine-9-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 C23H21NO4?
C23H21NO4 has a degree of unsaturation of 14. 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.
