1H-Benzimidazole-5,6-diamine (9CI) is a chemical compound with the molecular formula C7H7N3. It is a benzimidazole derivative, which is a class of organic compounds containing a benzene ring fused to an imidazole ring. 1H-Benzimidazole-5,6-diamine(9CI) is a diamine, meaning it contains two amine (NH2) functional groups. It has potential applications in the synthesis of pharmaceuticals and agrochemicals, as well as in scientific research as a building block for more complex organic molecules. Additionally, 1H-Benzimidazole-5,6-diamine may also have biological properties and therefore may be of interest in the development of new drugs. Due to its chemical properties, it is important to handle this compound with caution and in accordance with proper safety procedures.

Check Digit Verification of cas no

The CAS Registry Mumber 71209-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71209-21:
(7*7)+(6*1)+(5*2)+(4*0)+(3*9)+(2*2)+(1*1)=97
97 % 10 = 7
So 71209-21-7 is a valid CAS Registry Number.

Two Emissive Long-Lived Excited States of an Imidazole-Functionalized Ruthenium Dipyridophenazine Complex

Isakov, Dajana,Giereth, Robin,Nauroozi, Djawed,Tschierlei, Stefanie,Rau, Sven

, p. 12646 - 12653 (2019/10/11)

A ruthenium(II) polypyridine-type complex based on the dipyridophenazine ligand with a directly fused imidazole unit (L1, dipyrido[3,2-a:2′,3′-c]phenazine-10,11-imidazole) has been synthesized, and its electrochemical and photophysical properties have been studied. The cyclic voltammogram of [Ru(tbbpy)2(L1)]2+ (C1) (tbbpy is 4,4′-tert-butyl-2,2′-bipyridine) shows a cathodic shift of the phenazine-based reduction process compared to similar molecules, while the first detected reduction wave (-1.34 V vs Fc/Fc+) is assigned to the imidazole unit within the molecule. On the basis of the TD-DFT calculations, the strong visible absorption band exhibited by C1 is assigned to a metal-to-ligand charge transfer (MLCT) transition with a concurrent ligand-centered (LC) transition. At room-temperature, C1 features emission (φ = 0.04) from its lowest excited states with time constants of 1.2 and 18.3 μs. These lifetimes are assigned to emission processes from the 3MLCT and 3LC state, respectively. This is the first time that a long-lived dual emission has been observed for a ruthenium(II) complex bearing a directly fused extended π-system. Furthermore, the emission of C1 is quenched upon water addition. In contrast to related compounds based on a dipyridophenazine ligand, the excited state energy is not shifted, and the lifetime is drastically decreased to 169 ns.

Molecular "light switch" for G-quadruplex DNA: Cycling the switch on and off
