In 2019,Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy included an article by Ta, Sabyasachi; Das, Sudipta; Ghosh, Milan; Banerjee, Mahuya; Hira, Sumit Kumar; Manna, Partha Pratim; Das, Debasis. Recommanded Product: 1H-Benzo[d]imidazol-2-amine. The article was titled 《A unique benzimidazole-naphthalene hybrid molecule for independent detection of Zn2+ and N-3 ions: Experimental and theoretical investigations》. The information in the text is summarized as follows:
Single crystal X-ray structurally characterized benzimidazole-naphthalene hybrid (NABI) functions as a unique dual analyte sensor that can detect Zn2+ cation and N-3 anion independently. The NABI forms chelate with Zn2+ to inhibit internal charge transfer (ICT) and -CH=N- isomerization resulting chelation enhanced fluorescence (CHEF). On the other hand, the sensing of N-3 is based on formation of supramol. H-bonded rigid assembly. The association constant of NABI for Zn2+ and N-3 ions are 19 × 104 M-1 and 11 × 102 M-1, resp. Corresponding limit of detections (LOD) are 6.85 × 10-8 and 1.82 × 10-7 M, resp. NABI efficiently detects intracellular Zn2+ and N-3 ions with no cytotoxicity on J774A.1cells under fluorescence microscope. DFT studies unlock underlying spectroscopic properties of free NABI and Zn2+/N-3 bound forms. The experimental process involved the reaction of 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Recommanded Product: 1H-Benzo[d]imidazol-2-amine)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Recommanded Product: 1H-Benzo[d]imidazol-2-amine
