On January 26, 2017, Suzenet, Franck; Sirbu, Doina; Guillaumet, Gerald; Bonnet, Pascal published a patent.Recommanded Product: 5-Methoxy-1H-pyrazole The title of the patent was Preparation of new polyazo heterocyclic compounds and their uses as fluorescent chromophores. And the patent contained the following:
The invention relates to the preparation and use as chromophoric fluorescent of compounds of formula I wherein A1 is N or C(Y1); A2 is N or C(Y2); A3 is N or C(Y3); A4 is N or C(Y4); at least one of A1, A2, A3 and A4 representing N; X1 is N or C(Y5); X2 is N or C(Y6); X3 is N or C(Y7); and Y1, Y2, Y3, Y4, Y5, Y6 and Y7 are in particular selected independently of one another from H, electron-donating groups and electron-withdrawing groups. Example compounds, such as II were prepared by multistep procedures (shown) and evaluated for their photophys. properties (data shown). Compounds I are useful as fluorescent chromophores for detection of mols. of biol. origin. The experimental process involved the reaction of 5-Methoxy-1H-pyrazole(cas: 215610-30-3).Recommanded Product: 5-Methoxy-1H-pyrazole
