| Patent Claims: |
1. A crystalline compound, which is anhydrous (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol having a DSC endotherm at about 124° C. 2. The crystalline compound of claim 1, which has an X-ray powder diffraction pattern with peaks at one or more of about 4.0, 8.1, 9.8, 14.0 and/or 19.3 degrees 2Θ. 3. The crystalline compound of claim 2, which has an X-ray powder diffraction pattern with a peak at about 14.0 degrees 2Θ. 4. The crystalline compound of claim 1, which has an X-ray powder diffraction pattern that is substantially the same as that shown in FIG. 1. 5. The crystalline compound of claim 1, which has a Raman spectrum with peaks at one or more of about 3068, 2929, 2888, 2881, 1615, 1603, 1244, 1037, 692 and/or 372 cm−1. 6. The crystalline compound of claim 1, which has a Raman spectrum that is substantially the same as that shown in FIG. 2. 7. A crystalline compound, which is anhydrous (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol having a DSC endotherm at about 134° C. 8. The crystalline compound of claim 2, which has an X-ray powder diffraction pattern with peaks at one or more of about 4.4, 4.8, 14.5, 14.7, 15.5, 21.2, 22.1 and/or 23.8 degrees 2Θ. 9. The crystalline compound of claim 8, which has an X-ray powder diffraction pattern with a peak at about 4.4 degrees 2Θ. 10. The crystalline compound of claim 2, which has an X-ray powder diffraction pattern that is substantially the same as that shown in FIG. 3. 11. The crystalline compound of claim 2, which has a Raman spectrum with peaks at one or more of about 3061, 2927, 2877, 2864, 1605, 1038, 842, and/or 719 cm−1. 12. The crystalline compound of claim 2, which has a Raman spectrum that is substantially the same as that shown in FIG. 4. 13. A pharmaceutical dosage form comprising an active pharmaceutical ingredient and a pharmaceutically acceptable excipient or diluent, wherein the active pharmaceutical ingredient is crystalline anhydrous (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol having an X-ray powder diffraction pattern with peaks at one or more of about 4.0, 8.1, 9.8, 14.0 and/or 19.3 degrees 2Θ. 14. A pharmaceutical dosage form comprising an active pharmaceutical ingredient and a pharmaceutically acceptable excipient or diluent wherein the active pharmaceutical ingredient is crystalline anhydrous (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol having an X-ray powder diffraction pattern having peaks at one or more of about 4.4, 4.8, 14.5, 14.7, 15.5, 21.2, 22.1 and/or 23.8 degrees 2Θ. |
