Abstract: The charge transfer interactions of dobutamine with p-benzoquinone and chloranil were investigated in ethanol medium, the reactions of Dobutamine with p-benzoquinone and chloranil are complete. The products have maximum absorption at 500 nm and 472 nm, respectively. The apparent molar absorptivities are 1.81×104 for p-penzoquinone and 4.22×10⁴ for chloranil. The method proposed on the basis of the above results was applied to the determination of Dobutamine injection and the results were satisfatory.
