Abstract
A method of preparing metal mesoporphyrin compounds is described. A metal mesoporphyrin compound may be formed by forming a novel mesoporphyrin IX intermediate compound and then converting the mesoporphyrin IX intermediate to a metal mesoporphyrin compound through metal insertion. The novel intermediate compound may be formed by a catalytic hydrogenation of hemin in acid and subsequent recovery.
