Phenylphosphinic acid Usage And Synthesis
| Chemical Properties | white crystals or crystalline powder |
| Uses | Antioxidant, intermediate for metallic-salt formation, accelerator for organic peroxide catalysts. |
| Uses | 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. |
| General Description | Phenylphosphinic acid is also known as phenylphosphonous acid. Kinetics of oxidation of phenylphosphinic acid by metal and non metal oxidants was investigated in a study.2 |
| Purification Methods | Crystallise it from H2O (solubility is 7.7% at 25o). Also purify it by placing the solid in a flask covered with dry Et2O, and allowed it to stand for 1day with intermittent shaking. Et2O is decanted off and the process repeated. After filtration, excess Et2O is removed in a vacuum. It has also been recrystallised from *C6H6.
