Abstract A new ligand 2-[2′-(5-Nitrothiazolyl) azo]-4-methoxyphenol (NTAMP) was
synthesized using the coupling reaction between 2-amino-5-nitrothiazole and 4 …

In this research investigation, novel isoxazolone-thiazole based azo dyes (Io1-Io4) were
synthesized by a conventional azo coupling reaction at 0-5° C. The structure elucidation was …

Background: Heterocyclic compounds have gained attention due to their growing demand
against various infectious diseases, but their synthesis with hazardous chemicals, costly …

In the present work, Polarization, Excited States, Trans–Cis (E→ Z) Isomerization Properties
and Anisotropy of Thermal and Electrical Conductivity of the 4-(phenyldiazenyl) aniline in …

The dried layered double hydroxides (LDHs), have poor dispersibility, and are difficult to
recycle in water. In this study, the cobalt-aluminum LDHs were prepared by hydrothermal …

Abstract A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-
pyridones were synthesized and characterized by FT–IR, 1 H and 13 C NMR, UV–Vis, and …

In the pursuit of innovation, four distinct mono Azo dyes D 1-D 4 were synthesized. These
dyes were crafted through a coupling reaction involving 1-naphthol, resorcinol and salicylic …
