A high performance liquid chromatography tandem mass spectrometry/mass spectrometry(HPLC-MS/MS)protocol was developed for the determination of diphenylamine(DPA).Four productions of DPA were selected for qualitative a...
Based on the location of bromine substituents and conjugation matrix, a new substituent po- sition index ~X not only was defined, but also molecular shape indexes Km and electronega- tivity distance vectors Mm of diph...
The title compound, methyl 2-(diphenylamino)-4-phenyl-1,3-thiazole-5-carboxylate, was synthesized and studied by single-crystal X-ray diffraction method. The structure of the product was confirmed by IR, 1H- and 13C...
