Methylphosphonic acid is an organophosphorus compound with the chemical formula CH₃P(O)(OH)₂. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.
