Merck, 439770-5G, Gadolinium(III) chloride

General description
Gadolinium(III) chloride is a white inorganic halide hygroscopic solid soluble in water. Gd³⁺ species are particularly intriguing because they possess the highest known number of unpaired spins among all elements. The exceptional magnetic properties and symmetry of Gd³⁺ make it a valuable component in both NMR spectroscopy and MRI applications. It is widely used as a dopant/precursor to enhance the optical and magnetic properties of various materials used in MRI contrast agents, electronic devices, and phosphors.
Application
Gadolinium(III) chloride can be used:
As a precursor to synthesize Gd metal nanoparticles.
As a dopant to prepare CdSe nanoparticles as a contrast agent for optical and magnetic resonance imaging applications.
To prepare Gd-Hematoporphyrin monomethyl ether(HMME) phosphors for oxygen sensing.
To fabricate radioluminescent silica optical fibers via surface plasma chemical vapor deposition (SPCVD), for magneto-optical devices.
