Thermal analysis of a polymorphic azo dye derived from 2-amino-5-nitrothiazole
An azo dye, derived from 2-amino-5-nitrothiazole and a substituted N,N-dimethyl aniline, was studied by various techniques. Two sets of proton signals were obtained by NMR in CDCl3 solution, suggesting that two polymorphs coexist, however only one set of signals is observed in DMSO solution. Differe...
