Extraction of Brazilin: you can grind the chemical into sawdust, then soak the powder in lye or a hot solution of alum, either of which extracts the color better than plain water alone.

Uses of Brazilin: it can be used as a reagent for determinating iron and acid and alkali indicatorit. And it also can be used in dyeing plant specimens and nuclei. In addition, it can react with bromomethyl-benzene to get 3,9,10-tris-benzyloxy-7,11b-dihydro-indeno[2,1-c]chromen-6a-ol. This reaction will need reagent K₂CO₃ and solvent acetone. The reaction time is 18 hours by heating. The yield is about 85%.
