Useful:

• Canonical SMILES: C1=CC=C(C=C1)[P+](=O)O
• Uses: Antioxidant, intermediate for metallic-salt formation, accelerator for organic peroxide catalysts. Coproporphyrin I-15N4 is an intermediate in the synthesis of Coproporphyrin I-15N4 Sodium BIsulfate Salt (C685402). Labelled Coproporphyrin I. Coproporphyrin I is a porphyrin, a naturally occuring aromatic heterocyclic marcomolecule. The ratio of Coproporphyrin I and Coproporphyrin III provides a useful biochemical marker for distinguishing familial and sporadic porphyria cutanea tarda. Coproporphyrin I also serve as a biomarker of environmental toxicity and susceptibility in autism.
