Investigation on the endothermic event of cephalexin monohydrate in differential scanning calorimetric curve

Multicomponent solid forms of antibiotic cephalexin towards improved chemical stability

“…Generally an exotherm represents the possibility of either recrystallization or decomposition of a compound. In the case of CPX monohydrate, a broad endotherm in the range of 60–74 °C represents dehydration followed by possible decomposition as indicated by the sharp exotherm at 198.6 °C 34 (Fig. 4).…”
