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

The experimental FT-IR (4000-400 cm(-1)) and FT-Raman (3500-100 cm(-1)) spectra of 4-Methylmorpholine were recorded. The observed bands were interpreted with the aid of normal coordinate analysis and force field calculations based on density functional theory (DFT) using B3LYP functional theory

Investigations of respiratory symptoms among workers in a factory producing polyurethane foam included measurement of air pollution with amines and isocyanates and a simultaneous health investigation of the exposed workers. An increased bronchial reactivity to inhaled methacholine was found in

N-methylmorpholine, which is used as a catalyst in polyurethane foams producing, in solvents, stabilizing agents, and corrosion inhibitors, was administered to female rats by gavage at 100, 200, 600, and 900 mg/kg during organogenesis. It did not exhibit selective toxicity

The N-methylmorpholine levels in workroom air in a polyurethane foam factory were determined by two methods in which midget impinger flasks were used for sampling. The analyses were performed by gas chromatography and isotachophoresis. The values obtained by the gas
