(Aminomethyl)phosphonic acid is used in the synthesis of (acetylamino-methyl)-phosphonic acid through a reaction with acetic anhydride. It is used in the development of immobilized metal affinity chromatography columns based on organic-inorganic hybrid silica monoliths. This compound is a degradation product of glyphosate, a herbicide. Additionally, (Aminomethyl)phosphonic acid serves as a phosphonate agent in wastewater treatment. It inhibits the activity of enzymes involved in bacterial cell wall synthesis and energy metabolism, such as aminoglycoside-3′-phosphotransferase. Notably, (Aminomethyl)phosphonic acid exhibits neurotoxicity towards neuronal cells, with prolonged exposure leading to neuronal death.
