Synthesis of several potential impurities and/or degradationproducts of zaleplon is identified. All the prepared compounds were unambiguously identified by NMR techniques. Spectral characteristics (IR, UV, MS) of these compounds are also given. J. Heterocyclic Chem., (2010).

The invention relates to novel immunogens, antibodies, methods and kits for use in immunoassays to detect and quantify zaleplon, metabolites of zaleplon and indiplon. These are the first described immunoassays for these compounds and have greater sensitivity than alternative analytical techniques.
