The triazoloquinazole fused-ring system of the title compound, C10H7ClN4O2S, is essentially planar (r.m.s. deviation = 0.009 Å). In the methylsulfonyl substituent, the two S—O bonds are of equal length [1.402 (2) Å]. In the crystal, adjacent molecules interact weakly through Cl⋯N contacts [ca 3.197 (2) Å].
