Product Overview:
Dimethylphosphine oxide is an organophosphorus compound, a simple secondary phosphine oxide. It exists primarily in the phosphine oxide form rather than the tautomeric hydroxy form, and is soluble in polar organic solvents. It is a common reagent in organic synthesis, especially for coupling reactions and the preparation of more complex phosphorus-containing compounds.
Applications:
  • Key building block for the synthesis of Lenacapavir and other pharmaceutical intermediates
  • Used in organic synthesis as a reagent for cross-coupling and phosphorus functional group transformations
  • Applied in the preparation of phosphine ligands and other organophosphorus compounds
Additional Information:
  • Full analytical documentation (¹H NMR, GC-MS, elemental analysis) available upon request
  • Custom synthesis and bulk production quantities are available
  • For research and laboratory use only; not intended for direct human administration.
