Description

Phosphine Oxide, Tris(4-Bromophenyl)- CAS NO 900-99-2 is a high-purity organophosphorus compound characterized by its three brominated phenyl groups attached to a central phosphine oxide core. This specific molecular architecture makes it a valuable intermediate and ligand in advanced chemical synthesis and materials science. It is primarily sought after by research institutions and industrial manufacturers engaged in the development of specialty polymers, flame retardants, and photoactive materials.

Application

• As a key intermediate in the synthesis of advanced organic materials and specialty chemicals.
• Utilized as a ligand or precursor in organometallic chemistry and catalysis research.
• Potential use as a flame retardant additive or synergist in polymer formulations due to its bromine and phosphorus content.
• Employed in the research and development of photoinitiators and materials for optoelectronic applications.
• Acts as a building block for pharmaceuticals and agrochemicals requiring a brominated phosphine oxide moiety.
• Used in academic and industrial R&D laboratories for exploring new synthetic methodologies.
