Abstract
Pharmaceutical salt-forming acid 1-hydroxy-2-naphthoic acid (HNA) is widely used in pharmaceutical co-crystal preparation. In this work, we report a new polymorph of HNA obtained during attempted co-crystallization experiments. The reported form and the new form were fully characterized and their thermodynamic relationship was also established to be monotropic with the new form being the more stable form.
