has been used to investigate the polymorphism of sulfathiazole. The approach provides a
unique insight into the polymorphic transformations and thermal behaviour exhibited by this
compound. The results of the experiments show that sulfathiazole tends to crystallize as
mixtures of polymorphs, although the literature methods of producing pure polymorph were
followed. The use of light intensity profile obtained from the HSM images, as an alternative
way to present results of HSM analysis is also introduced here. It was found to correspond
very well with the DSC thermogram.
