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

[edit] Synthesis
The reaction of curcumin with borates in presence of oxalic acid produces rubrocurcumin.[1]
[edit] Characteristics
Rubrocurcumin produces a red colored solution.
Rubrocurcumin is a neutrally charged composition, while rosocyanine is build from ions. In rubrocurcumin, one molecule curcumin is replaced with oxalate compared to rosocyanine.
Complexes with boron such as rubrocurcumin are called 1,3,2-dioxaborines.[1]
