11-Hydroxyundecylphosphonic acid, 99% (HPLC)

Not available outside of the UK & Ireland.

Application

HUPA is mainly used as a spacer/linker that forms a SAM on titanium oxide (TiO₂) surfaces to immobilize the surface atoms for the formation of biocompatible materials for biomedical applications. It can also be used to functionalize the silicon-photonic resonators for biosensing applications.

An organophosphonate surface modifier for label-free and low-cost biosensing applications;Organophosphonic acid self-assembled monolayers (SAMs);A hydroxyalkylphosphonate monolayer used to covalently bind primary amine groups in protein domains using chloroformate-derived crosslinking

General description

11-Hydroxyundecylphosphonic acid (HUPA) is an alkyl phosphonic acid that forms a self-assembled monolayer (SAM) on a variety of metal oxides and metal surfaces. It forms a hydroxyl terminated SAM that provides a physiological stability and controls the surface density of the coating.
