Abstract
A combination of differential scanning calorimetry and hotstage microscopy with image analysis has been used to investigate the polymorphism of sulfathiazole The use of light intensity profiles obtained from the HSM images as an alternative way to present results of the HSM analysis was found to be useful in describing and verifying thermal events 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 crystallise as mixtures of polymorphs even though the literature methods for producing pure polymorph were followedThe authors thank Dr David Ross of the Department of Materials Loughborough University for the use of the HSM system Financial support provided by the Engineering and Physical Sciences Research Council EPSRC UK grant EP/E022294/1 is gratefully acknowledged One of the authors MRAB is grateful to the Malaysian Ministry of Higher Education and the International Islamic University Malaysia for a scholarship
