摘要

A new polymorph of dehydroepiandrosterone, also known as DHEA or prasterone, was found and designated form FVI. Form FVI is anhydrous and nonsolvated, and is less thermodynamically stable than the known form FI under ambient conditions. The X-ray powder diffraction patterns of FI and FVI are so similar that this technique is inadequate to determine if samples contain pure FI, pure FVI, or mixtures of the two. However, the forms can be differentiated by solid-state NMR spectroscopy. The crystal structure of FVI was determined from X-ray powder diffraction data using a combination of proprietary SSCI software and the Cambridge Crystallographic Data Centre's program DASH.
