Quality Control of 3-HydroxybenzaldehydeIn 2020 ,《Synthesis and characterization of a novel and green rod-like magnetic ZnS/CuFe2O4/agar organometallic hybrid catalyst for the synthesis of biologically-active 2-amino-tetrahydro-4H-chromene-3-carbonitrile derivatives》 appeared in Applied Organometallic Chemistry. The author of the article were Bahrami, Shahrzad; Hassanzadeh-Afruzi, Fereshte; Maleki, Ali. The article conveys some information:
The magnetic biocompatible rod-like ZnS/CuFe2O4/agar organometallic hybrid catalyst was designed and prepared based on a natural macromol. (agar) through a green and convenient method using inexpensive, nontoxic, and easily available substances. Then, the as-prepared catalyst was characterized by several techniques such as Fourier transform-IR spectroscopy, energy-dispersive X-ray anal., SEM image, transmission electron microscopy, vibrating sample magnetometry curve, X-ray diffraction pattern, and thermogravimetric anal. Eventually, the catalytic application of the ZnS/CuFe2O4/agar nanobiocomposite was assessed in sequential Knoevenagel condensation-Michael addition reaction of dimedone, malononitrile, and different substituted aromatic aldehydes for the synthesis of 2-amino-tetrahydro-4H-chromene-3-carbonitrile derivatives Some notable strengths of this environmentally benign catalyst include simplicity of catalyst preparation and separation, affording desired products with satisfactory yields (81%-97%) in very short reaction times (3-18 min), and with no need for complicated work-up processes. Exptl. tests showed that the catalyst can be successfully reused after five sequential runs without significant reduction in its catalytic efficiency.3-Hydroxybenzaldehyde(cas: 100-83-4Quality Control of 3-Hydroxybenzaldehyde) was used in this study.
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Quality Control of 3-Hydroxybenzaldehyde
