Abstract: In the title compound, C₂₃H₂₆Cl₂N₅O₅P, the P atom adopts a distorted tetrahedral coordination. The terminal ethyl carboxylate group is almost coplanar with the plane of the pyrazole ring. Intramolecular N-HO hydrogen bonds influence the overall conformation of the molecule. C-H Interactions contribute to the crystal packing.
