(2-Aminoethyl)phosphonic acid Usage And Synthesis

Chemical Properties	WHITE TO BEIGE CRYSTALLINE POWDER
Uses	2-Aminoethylphosphonic acid was used as a growth medium for the marine bacterium Roseovarius nubinhibens ISM.
Definition	ChEBI: A phosphonic acid in which the hydrogen attached to the phosphorus of phosphonic acid is substituted by a 2-aminoethyl group.
Synthesis Reference(s)	Journal of the American Chemical Society, 69, p. 2112, 1947 DOI: 10.1021/ja01201a012
General Description	The surface of gold nanoparticles (Au NPs) were functionalized with 2-aminoethylphosphonic acid that exhibited calcium affinity which enabled targeted delivery of Au NPs to calcified tissue.
