(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.
