So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Jiao, Xinyue; Marin, Luminita; Cheng, Xinjian researched the compound: 2,4-Dimethyl-1H-pyrrole( cas:625-82-1 ).Recommanded Product: 625-82-1.They published the article 《Fluorescent cellulose/testing paper for the sensitive and selective recognition of explosives 2,4,6-trinitrophenol and 2,4-dinitrophenylhydrazine》 about this compound( cas:625-82-1 ) in Journal of Photochemistry and Photobiology, A: Chemistry. Keywords: trinitrophenol dinitrophenylhydrazine cellulose sensor etherification. We’ll tell you more about this compound (cas:625-82-1).
2,4,6-trinitrophenol (TNP) and 2,4-dinitrophenylhydrazine (DNH) are harmful to the environment and human beings. Trace detection of TNP and DNH is worth of developing facile methods. In this work, cellulose powder and filter paper based fluorescence sensor are synthesized. Firstly, NH2CH2CH2- was introduced into cellulose through etherification reaction, and at the same time, a small mol. BODIPY with -CHO was synthesized. Then BODIPY was incorporated into cellulose by Schiff base reaction to obtain fluorescent macromol. probes. These fluorescent cellulose sensors can efficiently identify TNP and DNH, with the lowest detection limits of 2.8 x 10-7 M and 1.6 x 10-7 M, resp. Fluorescent filter paper is obtained via the same route. They also exhibit TNP and DNH identification ability. The method developed in filter paper not only expands the application range of cellulose, but also can efficiently identify the pollutants TNP and DNH, which is of great significance in theory and practical applications.
