Abstract: This work presents UV first derivative spectrophotometry as a precise, accurate, and feasible method for simultaneous determination of diminazene diaceturate and phenazone in bulk and dosage forms.The absorbance values of diminazene diaceturate and phenazone aqueous mixture were obtained at 398nm and 273 nm, respectively.The developed method was proved to be linear over the concentration ranges (2–10) 𝜇g/mL and (2.496–12.48) 𝜇g/mL for diminazene diaceturate and phenazone, respectively, with good correlation coefficients (not less than 0.997). The detection and quantitation limits were found to be (LOD = 0.63 and 0.48 𝜇g/mL; LOQ = 1.92 and 1.47 𝜇g/mL, resp.).The developed method was employed for stability studies of both drugs under different stress conditions. Diminazene diaceturate was prone to degrade at acidic pH via first-order kinetics. The degradation process was found to be temperature dependent with an activation energy of 7.48 kcal/mole. Photo-stability was also investigated for this drug.
