Extraction spectrophotometric determination of sulfidic yperite, based on the reaction with four phthaleins, was developed. The method is technically simpler than the determination of yperites with reagent T-135 (alkaline-aqueous ethanolic thymolphthalein solution) because it does not require heating at 80C, cooling and acidification of the reaction mixture. Selection of the appropriate phthalein, and particularly optimization of the reagent composition and extraction of the coloured reaction product in chloroform, markedly increased the selectivity of the determination of yperites (HD, HN-3). The reaction is performed in a medium of increased polarity due to the low content of alcohol which enables the reaction to proceed at temperatures of 5-20C without any marked loss of sensitivity. Using 1H and 13C NMR spectroscopy, the reaction products of HD and o- cresolphthalein were identified and an ionic mechanism for the reaction of HD with phthaleins is suggested.

4265-25-2, Name is 2-Methylbenzofuran, belongs to benzofurans compound, is a common compound. SDS of cas: 4265-25-2In an article, once mentioned the new application about 4265-25-2.

The conditions used to generate wood smoke for the purpose of smoking food greatly affect the flavor character of the resulting food. The relationships between wood type and smoke generation conditions and the resulting volatile composition and flavor character are not well understood. The objective of this study was to characterize the volatile organic compounds (VOCs) in K?nuka (Kunzea ericoides) wood smoke. Smoke was generated at four temperatures (180?480 C) under either air or nitrogen using a lab-scale smoke generator. VOCs were extracted in-line by stir bar sorptive extraction (SBSE) and analyzed by gas chromatography mass spectrometry (GC?MS). More than three hundred compounds were detected, of which phenols were the dominant class, followed by ketones and aldehydes. Temperature had a greater impact than either air or nitrogen on the VOC profile, however some large compound-specific effects were observed. Comparison of 2,6-dimethylphenol, creosol, furfural, 2-methoxy-4-propylphenol, 2-furanmethanol and 4-hydroxy-3,5-dimethoxybenzaldehyde demonstrated that their intensities varied with the smoke generation temperature under both air and nitrogen, implying that different aroma profiles can be developed.

A series of new ecteinascidin pentacyclic-derived compounds bearing aryl carboxylic amide side chains at C-22 have been designed and synthesized. The cytotoxicity evaluation confirmed their potent antitumor activity by use of eight different cell lines. Studies on the structure-activity relationship of them showed that the chemical structure of C-22 pendants have great effects on the tumor-killing activity. Notably, Compounds 6, 7 and 8 with benzo[b]thiophene-2-carboxamide pendants exhibited excellent broad-spectrum antitumor activity with the low IC50 values of 10?7 M.

652-12-0, Name is Tetrafluorophthalic anhydride, belongs to benzofurans compound, is a common compound. Computed Properties of C8F4O3In an article, once mentioned the new application about 652-12-0.

A series of zinc(II) porphyrinimide dyads (ZP-Im), in which an electron donating ZP moiety is directly connected to an electron accepting imide moiety in the meso position, have been prepared for the examination of energy gap dependence of intramolecular electron transfer reactions with large electronic coupling. The nearly perpendicular conformation of the imide moiety towards the porphyrin plane has been revealed by X-ray crystal structures. The energy gap for charge separation, 1Zp*-Im ? ZP+ – Im-, is varied by changing the electron accepting imide moiety to cover a range of about 0.8 eV in DMF. Definitive evidence for electron transfer has been obtained in three solvents (toluene, THF, and DMF) through picosecond-femtosecond transient absorption studies, which have allowed us to determine the rates of photoinduced charge separation, 1ZP*-Im?ZP+-Im-, and subsequent thermal charge recombination ZP+-Im-? ZP-Im. The free-energy gap dependence (energy gap law) has been probed from the normal to the nearly top region for the charge separation rate alone, and only the inverted region for the charge recombination rate. Although both of the energy gap dependencies can be approximately reproduced by means of the simplified semiclassical equation, when we take into consideration the effect of the high frequency vibrations replaced by one mode of averaged frequency, many features, including the effects of solvent polarity and the electron tunneling matrix element on the energy gap law, differ considerably from those of the previously studied porphyrin – quinone systems, which have weaker interchromophore electronic interactions.
