Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Sirohydrochlorin is a macrocyclic metabolic intermediate in the biosynthesis of corrin, precursor to the tetrapyrrole pigment and cofactor F430. It is a yellow compound. Its biosynthetic precursor is uroporphyrinogen III, the progenitor of all natural tetrapyrroles.[1]
