苯膦酸，Phenylphosphinic Acid

Phenylphosphinic Acid, also known as Phosphinic Acid, is an organophosphorus compound that appears as a white crystalline solid.

Phenylphosphinic Acid is a moderately strong acid that readily decomposes at high temperatures, producing toxic gases.

It is a multi-functional platform compound that, due to its extremely strong chelating and reactive properties, has become a key intermediate and additive.This has enabled efficient flame retardation of materials, separation and purification of metals, surface functional modification, and the construction of pharmaceutical molecules.
