You could be based in a university, combining chemical research with teaching; in a pharmaceutical company, working on developing and trialing new drugs; helping to ensure national healthcare provision keeps pace with new discoveries. , Recommanded Product: 4-Chloro-2-nitroaniline, 89-63-4, Name is 4-Chloro-2-nitroaniline, molecular formula is C6H5ClN2O2, belongs to naphthyridine compound. In a document, author is Zhou, YM, introduce the new discover.
A new fluorescent functional monomer DMAAN has been designed and synthesized for the first time. The monomer was expected to bind with cytosine via complementary hydrogen bonding under certain experimental conditions. The synthetic procedure of DMAAN is as follows. A suspension of 2,6-diaminopyridine in phosphoric acid was added to acetylacetone. The mixture was warmed for thirty minutes on a steam-bath. Then 2, 4-dimethyl-7-amino-1,8-naphthyridine (DMAN, mp 216-218 degrees C) was obtained. DMAAN was prepared by the reaction of DMAN with acryloyl chloride in chloroform and triethylether mixed solvent. Acryloyl chloride in anhydrous chloroform was added dropwise over 30 minutes with constant stirring at 4 degrees C. The melting point of the final product was 239-241 degrees C. Mass spectrometry and proton NMR were used to confirm the chemical structure of DMAN and DMAAN. The products were also characterized by UV and fluorescence spectrometry.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 89-63-4 is helpful to your research. Recommanded Product: 4-Chloro-2-nitroaniline.
