5,6-Dimethyl-1H-benzo[d]imidazole

5,6-Dimethylbenzimidazole is a key metabolic intermediate in riboflavin biosynthesis, serving as a precursor for alpha-ribazole and subsequently for cobamide cofactors. It is utilized in research on bacterial vitamin B12 synthesis and as a biochemical tool for studying related enzymatic pathways, such as those involving nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase.
