  • Solid forms of tin ethyl etiopurpurin and processes for producing such forms
    Patent number: 6605606
    Abstract: Solid forms of tin ethyl etiopurpurin (SnET2), including crystalline form I, crystalline Form II, disordered Form II, and an amorphous form are disclosed. Also disclosed are the 1,2-dichloroethane solvate of SnET2 and the N,N-dimethylformamide solvate of SnET2. These solid forms of SnET2 are useful as pharmaceuticals that exhibit pharmacological activity when irradiated with light and thus are useful in photodynamic therapy. Also disclosed are methods for making these solid forms of SnET2 and pharmaceuticals including these solid forms of SnET2.
