Safety of 2-Hydroxy-4-methoxybenzaldehydeIn 2019 ,《Synthesis of new TCH/Ni-based nanocomposite supported on SBA-15 and its catalytic application for preparation of benzimidazole and perimidine derivatives》 was published in Applied Organometallic Chemistry. The article was written by Kalhor, Mehdi; Rezaee-Baroonaghi, Fahimeh; Dadras, Akbar; Zarnegar, Zohre. The article contains the following contents:
A stable nickel-decorated SBA-15 nanocomposite (Ni/TCH@SBA-15) was synthesized through surface modification of silica nanoparticles with 3-chloropropyltriethoxysilane (CPTES) and thiocarbohydrazide (TCH) followed by metal-ligand coordination with Ni(II). The structure of this organometallic nanocomposite was characterized by Fourier transform-IR, field emission-SEM, EDAX, transmission electron microscopy, at. absorption spectroscopy and N2 adsorption-desorption (Brunauer-Emmett-Teller) techniques. The catalytic performance of Ni/TCH@SBA-15 (NNTS-15) was determined for synthesis of 2-aryl-substituted benzimidazoles I [R1 = H, Me, NO2; R2 = H, 4-MeO, 2,3-di-Cl, etc.] and 2,3-dihydroperimidines II. The excellent yields within shorter reaction times, simplicity of catalytic methods, non-toxicity and clean reactions, mild reaction conditions and easy work-up procedure were important merits of these synthetic protocols. Moreover, the Ni(II) bonded to SBA-15 surface was stable under catalytic reaction conditions resulting in its efficient recycling and reuse. The experimental process involved the reaction of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Safety of 2-Hydroxy-4-methoxybenzaldehyde)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is the main component of root bark essential oil of Periploca sepium Bunge. It is a potential tyrosinase inhibitor present in African medicinal plants. 2-Hydroxy-4-methoxybenzaldehyde was used in the synthesis of Schiff base ligand.Safety of 2-Hydroxy-4-methoxybenzaldehyde
