Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 3731-53-1, Name is Pyridin-4-ylmethanamine, molecular formula is , belongs to pyridine-derivatives compound. In a document, author is Demircali, Aykut, Formula: C6H8N2.
Novel heterocyclic disazo dyes containing pyrazole and phenylpyrazole. part 1: Synthesis, characterization, solvent polarity and acid-base sensitive characteristics
A series of diazotised aniline and aniline derivative compounds were reacted with solution of malononitrile in pyridine at 0-5 degrees C were obtained 1a-1m compounds. Then 4-arylazo-3,5-diamino-1H-pyrazole (2a-2m) derivatives were synthesized by coupling arylazo malononitrile compounds with hydrazine. Finally, the synthesized pyrazole derivative 2a-2m compounds were again diazotised. By reacting these diazotised compounds with 3-amino-5-hydroxy-1-phenylpyrazole, the new thirteen heterocyclic disazo dyes (3a-3m) were joined the dye literature and the dye industry. The structures of these newly synthesized compounds were characterized using elemental analysis and spectroscopic methods such as Fourier transform infrared spectroscopy-Attenuated total reflectance (FT-IR-ATR), H-1-Nuclear magnetic resonance (H-1 NMR) spectroscopy and mass spectroscopy. Then solvatochromic properties and solvent effect in dimethyl sulfoxide, dimethyl formamide, acetonitrile, acetic acid, methanol and chloroform were investigated. In addition, the effects of organic and inorganic acids and bases on the absorption spectra of the compounds and the substituent effect of the phenyl ring-bound groups were investigated.

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 3731-53-1, in my other articles. Formula: C6H8N2.
