Cysteine residues in polypeptides are not easily identified during automated N-terminal sequence analysis. Reaction of cysteine side chains with 4-vinylpyridine and identification as the pyridylethylated phenylthiohydantion derivative (PE-PTH-Cys) were proposed. However, after this reaction a desalting step is necessary. If

During the analysis of "seized samples", suspected of containing 4-methylmethcathinone (mephedrone) and N-ethylcathinone (ethcathinone) additional compounds were observed in the GCMS chromatogram. These compounds were suspected to be the corresponding phenylacetone isomers of mephedrone and ethcathinone respectively. These isomers are
