2-Methyl-sulfonyl-1,2,4-triazolo[1,5-a]quinazolin-5(4H)-one.
The triazoloquinazoline fused-ring system of the title compound, C(10)H(8)N(4)O(3)S, is essentially planar (r.m.s. deviation = 0.027 Å). In the crystal, adjacent mol-ecules are linked by N-H⋯O(sulfon-yl) hydrogen bonds, generating a helical chain running along the b axis.
