Dihydrosirohydrochlorin is a macrocyclic metabolic intermediate in the biosynthesis of corrin, precursor to the tetrapyrrole pigment and cofactor F430. In terms of its biosynthesis, it is produced by dimethylation is uroporphyrinogen III, the progenitor of all natural tetrapyrroles.^[1] Dehydrogenation, i.e., removal of H₂, of dihydrosirohydrochlorin gives sirohydrochlorin.
