Purification Methods Hemin is purified by recrystallisation from AcOH. Also, hemin (5g) is shaken in pyridine (25mL) till it dissolves, then CHCl3 (40mL) is added, the container is stoppered and shaken for 5minutes (releasing the stopper occasionally). The solution is filtered under slight suction, and the flask and filter are washed with a little CHCl3 (15mL). During this period, AcOH (300mL) is heated to boiling, and saturated aqueous NaCl (5mL) and conc HCl (4mL) are added. The CHCl3 filtrate is poured in a steady stream, with stirring, into the hot AcOH mixture and set aside for 12hours. The crystals are filtered off, washed with 50% aqueous AcOH (50mL), H2O (100mL), EtOH (25mL), Et2O and dried in air.
