摘要：

In the title molecule, C14H18ClN5O2S, the six atoms of the 1,6-ihydropyridazine ring are essentially coplanar (r.m.s. deviation = 0.008 (A) over circle), and the dihedral angle between this and the 1,3,4-thiadiazole ring is 62.06 (10)degrees. In the crystal, centrosymmetrically related molecules are linked by intermolecular CH-O hydrogen bonding to form a supramolecular dimer. The terminal ethyl group is statistically disordered over two positions.
