Human Carbonic Anhydrase inhibitors (CAIs) have been clinically used to treat a variety of disorders, such as cancer, obesity, haemolytic anaemia, glaucoma, retinopathy, and epilepsy. To develop a Carbonic Anhydrase inhibitor, Iminothiazoline analogue ((Z)-N-(3-([1,1'-biphenyl]-2-yl)-4-heptyl-4-hydroxythiazolidin-2-ylidene)-4-bromobenzamide) was synthesized and characterized. Single crystal X-Ray diffraction studies and Hirshfeld surface analysis (HSA) were conducted to find the exact molecular structure as well as intermolecular interactions. DFT Calculations indicated the soft and reactive nature of molecule. In-Vitro carbonic anhydrase inhibition studies showed the excellent inhibition potential of (Z)-N-(3-([1,1'-biphenyl]-2-yl)-4-heptyl-4-hydroxythiazolidin-2-ylidene)-4-bromobenzamide (IC
