Description

Lanthanum(3+) 2-Hydroxypropane-1,2,3-Tricarboxylate is the lanthanum salt of citric acid, a high-purity inorganic-organic coordination compound. This material is valued for its unique properties as a lanthanum source with enhanced solubility and bioavailability compared to simple inorganic salts. It is primarily utilized in advanced material synthesis, pharmaceutical research, and as a specialized catalyst or dopant. Industries requiring precise control over lanthanum ion release or specific chelating characteristics will find this compound essential for their formulations and processes.

Application

• Pharmaceutical Intermediates: Used in the research and development of lanthanum-based active pharmaceutical ingredients (APIs), particularly for phosphate-binding therapies.
• Catalyst & Catalyst Precursor: Serves as a precursor or co-catalyst in organic synthesis and polymerization reactions due to its Lewis acidic properties.
• Advanced Ceramics & Glass: Acts as a doping agent to modify the refractive index, electrical properties, and thermal stability of specialty optical glasses and ceramic materials.
• Chemical Vapor Deposition (CVD): Employed as a precursor for depositing lanthanum oxide (La₂O₃) thin films in semiconductor and electronic device manufacturing.
• Luminescent Materials: Functions as a host or dopant in the synthesis of phosphors and other photoluminescent materials.
• Water Treatment & Analysis: Utilized in analytical chemistry as a reagent and in experimental water treatment processes for phosphate sequestration.
• Stabilizer & Additive: Investigated for use as a stabilizer in polymers and as an additive in fuels or lubricants.
