## Abstract A series of phosphonic acid, 1,3,4‐thiadiazol‐2‐amine‐__N__‐alkyl have been synthesized by the reaction of 2‐amine thiadiazole, different aldehydes (or ketone), and phosphorous acid via the melting method or the solvent method. These compounds have been characterized by IR, ^1^H NMR, ^3
