We introduce then-pure projective (resp., injective) dimension of complexes inn-pure derived categories, and give some criteria for computing these dimensions in terms of then-pure projective (resp., injective) resolutions (resp., coresolutions) andn-pure derived functors. As a consequence, we get some equivalent characterizations for the finiteness ofn-pure global dimension of rings. Finally, we study Verdier quotient of boundedn-pure derived category modulo the bounded homotopy category ofn-pure projective modules, which is called ann-pure singularity category since it can reflect the finiteness ofn-pure global dimension of rings.
