This study focused on kinetic modelling of a specific type of multistep heterogeneous reaction comprising exothermic and endothermic reaction steps, as exemplified by the experimental kinetic curves for the thermal decomposition of (E)-4-Bromo-2-[(phenylimino)methyl]- phenol (4B2PMP) crystal. The crystal was grown by a slow evaporation method. The cell parameters and crystalline perfection of the grown crystal were studied by single and powder X-ray diffractions. Thermal stability and phase change of 4B2PMP crystal were analyzed by TG/DTA. The microhardness study has revealed the soft nature. UV-visible analysis reveals the wide range of optical window of the optical transmission from 199 nm to 1100 nm. The bandgap of the crystal is found to be 3.24 eV. The FESEM of the crystals was spherically shaped and consisted of a core-shell structure with internal aggregates. The antimicrobial activity of title crystal was tested against different microorganisms by disc diffusion method. The results reveal that the title compound have effective antimicrobial activities.
