Abstract: The instant disclosure provides crystalline forms of 1-benzoyl-4-[2-[4,7-dimethoxy-1-[(phosphonooxy)methyl]-1H-pyrrolo[2,3-c]pyridin-3-yl]-1,2-dioxoethyl]-piperazine, salts and solvates thereof. The present disclosure also generally relates to pharmaceutical compositions comprising the crystalline form(s), as well of methods of using the crystalline form(s) in the treatment of HIV and/or AIDS, and methods for obtaining such crystalline form(s).

Abstract: A laboratory sample plate for use in PXRD and other testing techniques includes a quartz body having substantially planar top and bottom surfaces that are parallel with each other. The quartz body includes a matrix of cylindrical apertures that are substantially perpendicular to the top and bottom surfaces. Each aperture has an upper opening at the top surface and a lower opening at the bottom surface of the plate body. A synthetic quartz bottom sheet is fused to the bottom surface of the quartz body. The quartz bottom sheet include respective portions that close the lower opening of each aperture in the quartz body, such that each aperture and respective portion of the bottom sheet together form a well for receiving a sample. Each aperture and respective portion of the bottom sheet are suitably dimensioned to perform a powder X-ray diffraction technique as well as microscopy and Raman spectroscopy on a sample contained in the well.
