Syntheses of formamidines and benzimidazoles was written by Mathias, L. J.;Overberger, C. G.. And the article was included in Synthetic Communications in 1975.SDS of cas: 58442-17-4 This article mentions the following:
The benzimidazoles I (R = 5(6)-Cl, 5(6)-Me, 5(6)-CO2H, 5(6)-benzimidazol-5(6)-yl) were prepared by cyclization of 4-RC6H3(NH2)2-1,2 with HCO2H in the presence of HCl and a strong acid resin. RNHCH:NR (R = p-O2NC6H4, p-H2NC6H4, 2-thiazolyl, 2-pyridyl) and I (R = 5(6)-Me, 4(7)-Me, 5(6)-NO2, 5(6)-COMe, 5(6)-CHO, 5(6)-Cl) were prepared by treating RNH2 or RC6H4(NH2)2-1,2 with Cl2CHOMe containing (Me3C)3N. In the experiment, the researchers used many compounds, for example, 1H-Benzimidazole-5-carbaldehyde (cas: 58442-17-4SDS of cas: 58442-17-4).
1H-Benzimidazole-5-carbaldehyde (cas: 58442-17-4) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.SDS of cas: 58442-17-4
