Rubrocurcumin is a red-colored dye that is formed by the reaction of curcumin and boric acid.[1]
Synthesis
[edit]The reaction of curcumin with borates in presence of oxalic acid produces rubrocurcumin.[2]
Characteristics
[edit]Rubrocurcumin produces a red-colored solution.
Rubrocurcumin is a neutral molecule, while rosocyanine is ionic. In rubrocurcumin, one molecule of curcumin is replaced with oxalate compared to rosocyanine.
Complexes with boron such as rubrocurcumin are called 1,3,2-dioxaborines.[2]
