3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2) belongs to pyridine derivatives. Pyridine has a conjugated system of six 锜?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H鐪塩kel criteria for aromatic systems. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C閳ユ弻 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Computed Properties of C6H6N2O3

Nanosize nickel hydroxide decorated 2-naphthalene sulfonic acid-doped polyaniline nanotubes nanocomposites (Ni(OH)2@NSA-PANI NCs) were successfully developed for the catalytic reduction of aromatic nitro compounds The Ni(OH)2@NSA-PANI NCs were synthesized by depositing Ni(OH)2 nanoparticles onto 2-naphthalene sulfonic acid doped PANI nanotubes surface. The resulting material was characterized using field emission SEM (FE-SEM), high resolution transmission electron microscopy (HR-TEM), powder X-ray diffraction (P-XRD), Fourier-transform IR spectroscopy (FT-IR), and XPS. The prepared nanocomposite showed a remarkable ability to catalytically hydrogenate aromatic nitro compounds using sodium borohydride (NaBH4) as hydrogen source in aqueous medium at room temperature Kinetic studies were performed using 4-nitrophenol (4-NP) as the model substrate, using the Langmuir-Hinshelwood model. The catalyst showed pseudo-first-order kinetics, with rate constants estimated between 0.08287 and 0.3649 min-1. Catalyst recyclability without reduced activity was demonstrated over 10 successive cycles. The optimized nanocomposite catalyst demonstrated a low activation energy barrier towards 4-NP reduction In the experiment, the researchers used many compounds, for example, 3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2Computed Properties of C6H6N2O3).
