What the paper reports

Electron diffraction established the previously unresolved structure of buspirone hydrochloride Form 2. The study also prepared 15 multicomponent solids, including cocrystals, an ionic cocrystal, and salts, and compared conformations and thermal behavior. This expands structural knowledge of a long-marketed drug and provides a solid-form exploration example without demonstrating improved clinical performance for the newly prepared materials.

Why this paper is included

Demonstrates that long-established APIs can still have unresolved polymorph structures, and links electron diffraction to a broader multicomponent solid-form development program.

The interpretation above is analysis, not a conclusion attributed to the original source.
