* Chemical purity (CP) is 98% or greater, unless otherwise specified. CPs are based upon HPLC and/or quantitative NMR analysis of the neat material. Each CP is accounted for in calculating the compound concentration for formulation. † Concentrations are achieved by reconstituting the dried down mix in 1 mL of solvent.
