CAS 1707-03-5

Diphenylphosphinic acid

Description:

Diphenylphosphinic acid, with the CAS number 1707-03-5, is an organophosphorus compound characterized by the presence of two phenyl groups attached to a phosphorus atom, which is also bonded to a hydroxyl group (–OH). This compound typically appears as a white crystalline solid and is soluble in organic solvents, but has limited solubility in water. Diphenylphosphinic acid exhibits acidic properties due to the presence of the phosphinic acid functional group, allowing it to donate protons in solution. It is often used as a ligand in coordination chemistry and as an intermediate in the synthesis of various phosphorus-containing compounds. Additionally, it can act as a flame retardant and is studied for its potential applications in materials science. The compound is relatively stable under normal conditions but should be handled with care due to potential toxicity associated with phosphorus compounds. Proper safety measures should be observed when working with diphenylphosphinic acid to mitigate any health risks.
