Description

Butylphosphonic Acid (CAS No. 3321-64-0) is a high-purity organophosphorus compound with the molecular formula C₄H₁₁O₃P, widely utilized in organic synthesis, coordination chemistry, and materials science. This versatile reagent features a phosphonic acid functional group bonded to a butyl chain, offering unique reactivity for metal chelation, surface modification, and catalysis. Our product is rigorously tested to ensure exceptional quality, with batch-specific analytical data (including ¹H NMR, ³¹P NMR, and HPLC) available upon request. Supplied as a white crystalline solid or colorless solution (custom concentrations available), it’s packaged under inert atmosphere to guarantee stability. Ideal for:

• Ligand design for transition metal complexes
• Self-assembled monolayer (SAM) formation on metal oxides
• Modification of nanoparticles and catalytic surfaces
• Intermediate for flame retardants and specialty polymers

Storage recommendation: Maintain under nitrogen at 2-8??C in tightly sealed containers. Hazard classification: Corrosive (GHS05).

Application

Butylphosphonic Acid serves as an effective coupling agent for surface functionalization of metal oxides like indium tin oxide (ITO) in electronic devices. Researchers employ it as a precursor for phosphonate-based metal-organic frameworks (MOFs) with tunable porosity. In catalysis, it acts as a ligand modifier to enhance selectivity in cross-coupling reactions. The compound also finds use in creating corrosion-resistant coatings through strong chemisorption on oxidized metal surfaces.
