Rubrocurcumin is a red-colored dye that is formed by the reaction of curcumin and borates.

Synthesis

The reaction of curcumin with borates in presence of oxalic acid produces rubrocurcumin.^[1]

Characteristics

Rubrocurcumin produces a red colored solution.

Rubrocurcumin is a neutrally charged composition, while rosocyanine is produced from ions. 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.^[1]
