Description

Bis[(1,1-Dimethylhexyl)Amino]Phosphine Oxide CAS NO 73790-33-7 is a specialized organophosphorus compound featuring a phosphine oxide core substituted with bulky, branched alkylamino groups. This unique structure makes it a highly effective and selective ligand or catalyst component in advanced chemical synthesis. It is primarily sought after by research and development teams in the pharmaceutical and fine chemical industries for demanding transition metal-catalyzed reactions. Its steric and electronic properties are key to enabling challenging cross-couplings and facilitating the synthesis of complex organic molecules.

Application

• As a ligand in transition metal catalysis, particularly for palladium- and nickel-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Buchwald-Hartwig amination).
• As a key intermediate or additive in the research and development of novel pharmaceutical active ingredients (APIs).
• In fine chemical synthesis for the production of complex, high-value organic compounds where high selectivity is required.
• As a specialized reagent in academic and industrial research laboratories exploring new catalytic methodologies.
• Potential use as a stabilizer or modifying agent in advanced material science applications, such as polymer synthesis.
