Product Name:Lanthanum(III) tris(2,2,6,6-tetramethyl-3,5-heptanedionate)
English Name:Lanthanum(III) tris(2,2,6,6-tetramethyl-3,5-heptanedionate)
CAS No.:14319-13-2
Aliases:Tris(2,2,6,6-tetramethyl-3,5-heptanedionato)lanthanum(III), Lanthanum(III) dipivaloylmethanide, La(DPM)₃
Molecular Formula:C33H57LaO6
Physical Properties:White to off-white crystalline powder. Soluble in organic solvents such as toluene, hexane, and ethanol; insoluble in water. Relatively stable in air, but recommended to be stored sealed under an inert atmosphere. Exhibits good thermal stability and volatility, and can be sublimed under vacuum.
Uses:Primarily used as a precursor for metal-organic chemical vapor deposition (MOCVD) and atomic layer deposition (ALD) to prepare lanthanum oxide (La₂O₃) thin films, which are widely applied in high-k gate dielectrics, catalyst supports, optical coatings, and microelectronic devices. It can also be used as a Lewis acid catalyst in organic synthesis.
Technical Specifications:
Purity ≥ 99.9%, with metal impurities controlled by ICP-MS analysis
Appearance: white to off-white crystalline powder
Molecular weight: 688.72
Melting point: 167–170°C; sublimable under vacuum
Soluble in toluene, hexane, ethanol, and other organic solvents; insoluble in water
