The FTIR and FT-Raman spectra of 2-amino-5-chloropyridine (ACP) has been recorded in the region 4000-400 and 3500-100 cm-1, respectively. The optimized geometry, frequency and intensity of the vibrational bands of ACP were obtained by the ab initio and density functional

Z-drugs such as zopiclone are increasingly involved in forensic cases. Its degradation occurs in solvents and biological fluids. It is assumed that hydrolysis largely accounts for the breakdown of zopiclone in aqueous media. Therefore, a stability study in blood at

Zopiclone is a common drug in forensic cases and it is frequently analyzed in biological materials using different analytical methods. Zopiclone is unstable in certain solvents and depending on storage conditions unstable in biological fluids; however its stability in human

A capillary electrophoretic enantioselective method with UV detection was developed and validated for the simultaneous quantification of zopiclone enantiomers and its impurities, zopiclone-N-oxide enantiomers, and 2-amino-5-chloropyridine, in tablets. The analytes were extracted from the tablets using ACN and were separated

The prevalence of zopiclone misuse in clients attending a methadone maintenance programme in Dublin through detection of its degradation product, 2-amino-5-chloropyridine (ACP) on urinalysis is outlined. Urine samples from all 158 clients were tested for the presence of ACP, opiates
