The purplish brown coloration of formyldesoxybenzoin by trivalent iron is specific to ferric ion in common elements. The composition of this coloration is Fe (C15H11O2)3 and was determined as the Fe+++ complex salt of formyldesoxyben-zoin (β-form), melting at 204.5-205°. From its facile solubility in organic solvents, this salt is assumed to be an inner complex compound. The coloration reactions due to the formation of this complex is advantageous in that the reaction can be carried out in dilute hydrochloric acid but is interfered by phosphoric acid and is not feasible in alkaline solution.
