Contact allergy to the UV-absorber 2-(2-hydroxy-5-methylphenyl)benzotriazole (Tinuvin P) was revealed in a patient with wrist dermatitis caused by a plastic watch strap. A high-performance liquid chromatography method was developed and subsequent chemical analysis showed the presence of Tinuvin P in

We report a 54-year-old female with allergic contact dermatitis from 2-(2-hydroxy-5-methylphenyl)benzotriazole (Tinuvin P) in a spandex tape sewn into underwear. Tinuvin P is used as an ultraviolet light absorber for stabilizing plastics and the other organic materials against discoloration and

We propose a scheme for molecule-based information processing by combining well-studied spectroscopic techniques and recent results from chemical dynamics. Specifically it is discussed how optical transitions in single molecules can be used to rapidly perform classical (Boolean) logical operations. In

2-(2,4-Dimethylphenyl)-2H-benzotriazole (1) has been synthesized in a three step procedure starting from 2,4-dimethyl-N-(2-nitrophenyl)benzamide via a 5-(2,4- dimethylphenyl)-1-(2-nitrophenyl)-1H-tetrazole intermediate. Its structure and those of Tinuvin P and 2-phenyl-2H-benzotriazole (5) have been studied by multinuclear NMR (1H-, 13C- and 15N-) in solution
