Use
Protoporphyrin IX (3,18-divinyl-2,7,13,17-tetramethylporphin-8,12-dipropionic acid, ooporphyrin) [553-12-8] M 562.7, pKEst ~ 4.8. Protoporphyrin IX is purified by dissolving (4g) in 98-100% HCOOH (85mL), diluting with dry Et2O (700mL) and keeping at 0o overnight. The precipitate is collected and washed with Et2O, then H2O, and dried in a vacuum at 50o over P2O5. It crystallises from aqueous pyridine and from Et2O in monoclinic, brownish-yellow prisms. The UV max values in 25% HCl are 557.2, 582.2 and 602.4nm. It is freely soluble in ethanolic HCl, AcOH, CHCl3, and Et2O containing AcOH. It forms sparingly soluble diNa and diK salts.
