The molecular weight of methyllycaconitine is 682.80 g/mole. The molecular weight of citric acid is 192.124 g/mole. The overall molecular weight of the salt complex is 874.94 g/mole, which corresponds to 1 mole of methyllycaconitine and 1 mole of citric acid. This calculation does not account for water content or purity. The certificate of analysis provides details on the number of moles of citric acid for each lot, as well as water content and purity, which may vary from lot to lot. The free base consists of one mole of methyllycaconitine.

The COA states “1.0 mol” of salt content, is that per mole of MLA? I need to know the exact MW of the salt complex in order to make a solution of known molarity. Do I assume there is one citrate molecule for each of MLA?
