摘要：
1. Polymorph of 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern substantially similar to that shown in FIG. 2.2. A polymorph of 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern comprising one or more peaks from the group consisting of peaks at 2θ of at least about 10.2, 11.9, 14.1, 14.5, 17.3, 22.2 and 28.1 degrees. 3. Polymorph 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern substantially similar to that shown in FIG. 3.4. A polymorph of 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern comprising one or more peaks from the group consisting of peaks at 2θ of at least about 7.5, 9.9, 12.3, 15, 23, 23.3, 24.6 and 28.4 degrees. 5. The polymorph according to claim 2, wherein the polymorph is a polymorph of 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern comprising two or more peaks from a peak at 2θ at least at least about 10.2 degrees, a peak at 2θ at least about 11.9 degrees, a peak at 2θ at least about 14.1 degrees, a peak at 2θ at least about 14.5 degrees, a peak at 2θ at least about 17.3 degrees, a peak at 2θ at least about 22.2 degrees, and a peak at 2θ at least about 28.1 degrees, and any combination thereof. 6. The polymorph according to claim 4, wherein the polymorph is a polymorph of 2-acetyl-4H, 9H-naphtho [2,3-b] furan-4,9-dione, characterized by an X-ray diffraction pattern comprising two or more peaks from a peak at 2θ at least at least about 7.5 degrees, peak at 2θ at least about 9.9 degrees, peak at 2θ at least m�1.
