Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 121-66-4, Name is 5-Nitrothiazol-2-amine121-66-4, introducing its new discovery.
Various hetarylazo dyes have been synthesized by coupling reactions between diazotised 2-amino-5-nitrothiazole and 2-chloroaniline, 1,3-dihydroxybenzene and N-phenyl naphthylamine. Spectral measurements were carried out in different solvents. The solvatochromic behaviour of the dyes in various solvents were evaluated. The 2-amino-5-nitrothiazole dye derivatives absorb maximally at longer wavelengths and are tinctorially stronger than the 1-naphthylamine dyes, although the former dyes have higher extinction coefficients. Also, the synthesized dyes exhibit positive solvatochromism so that the absorption bands of the dye, move towards longer wavelengths as the polarity of the solvent increases.

121-66-4, Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 121-66-4, in my other articles.
