Benzimidazole was discovered during research on vitamin B 12. The benzimidazole nucleus was found to be a stable platform on which drugs could be developed. [3] Benzimidazole is produced by condensation of o-phenylenediamine with formic acid, [4] or the equivalent trimethyl orthoformate: C 6 H 4 (NH 2) 2 + HC(OCH 3) 3 → C 6 H 4 N(NH)CH + 3 CH ...
Dietary supplements containing all eight are referred to as a vitamin B complex. Individual B vitamins are referred to by B-number or by chemical name, such as B 1 for thiamine , B 2 for riboflavin , and B 3 for niacin , [ 1 ] [ 2 ] while some are more commonly recognized by name than by number, such as pantothenic acid (B 5 ), biotin (B 7 ...

Vitamin B 12 is a coordination complex of cobalt, which occupies the center of a corrin ligand and is further bound to a benzimidazole ligand and adenosyl group. [18] Several related species are known and these behave similarly, in particular, all function as vitamins. This collection of compounds is sometimes referred to as "cobalamins".

It primarily serves to protect cobalamin (Vitamin B12) from acid degradation in the stomach by producing a HC-Vitamin B 12 complex. Once the complex has traveled to the more pH-neutral duodenum, pancreatic proteases degrade haptocorrin, releasing free cobalamin, which now binds to intrinsic factor for absorption by ileal enterocytes.
