Abstract

Thermogravimetry (TG), derivative thermogravimetry (DTG) and differential scanning calorimetry (DSC) were techniques used in this work to study thermal behavior of some analgesics: antipyrin, dipyrone and paracetamol. The results led to thermal stability data and also to interpretations concerning thermal decomposition. These techniques seem promising in quality control of active ingredients, excipients, etc., for the pharmaceutical industry.

Key words: thermal behavior; stability; TG; DSC; quality control
