Frequently asked questions
What is the molar mass of C16H13N5OS?
The molar mass of C16H13N5OS is 323.37 g/mol, calculated from standard atomic weights for 16 carbon atoms, 13 hydrogen atoms, 5 nitrogen atoms, 1 oxygen atom and 1 sulfur atom. The monoisotopic mass is 323.0841 Da.
How many compounds have the formula C16H13N5OS?
CompoundList lists 53 compounds with the molecular formula C16H13N5OS, including 3-[(6-Ethyl-4-thieno[2,3-d]pyrimidinyl)hydrazo]-2-indolone, 3-[(5,6-Dimethyl-4-thieno[2,3-d]pyrimidinyl)hydrazo]-2-indolone, 6-(1-Phenoxyethyl)-3-(pyridin-3-yl)[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole. 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 C16H13N5OS?
C16H13N5OS has a degree of unsaturation of 13. 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.
