Notably, the thermal behavior of INH-SYA cocrystal shows a single endothermic profile that is distinct and unique from the individual initiative materials [27], further demonstrating the formation of a new crystalline phase, in accordance with the observed PXRD results (vide infra). No appreciable endothermic event of the cocrystal between 50 and 300 °C also proves that the sample is anhydrous, which is in agreement with the analyses of SCXRD
