5,6dimethyl1hbenzo[d]imidazole

5,6-Dimethyl-1H-benzo[d]imidazole (5,6-Dimethylbenzimidazole) is an intermediate in Riboflavin metabolism and is the penultimate step in the synthesis of alpha-Ribazole. It is converted from Riboflavin and subsequently transformed into N1-(5-Phospho-alpha-D-ribosyl)-5,6-dimethylbenzimidazole by the enzyme nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase (EC 2.4.2.21).
