Let $H$ be a faithfully projective Hopf algebra over a commutative ring $k$ . In [8, 9] we defined the Brauer group $\text{BQ}(k,H)$ of $H$ and an homomorphism $\pi $ from Hopf automorphism group $\text{Au}{{\text{t}}_{\text{Hopf}}}(H)$ to $\text{BQ}(k,H)$ . In this paper, we show that the morphism $\pi $ can be embedded into an exact sequence.
