2,6-Di fluoro Dolutegravir

2,6-Di fluoro Dolutegravir is a dipyrimidinylpyrimidine-based API impurity featuring 2,6-difluoro substitution on the aryl ring of the parent Dolutegravir scaffold. The structure incorporates a 1,3,5-triazine core linked to a carboxamide side chain and a 4-amino-1,2,4-triazole-1-acetic acid moiety. The fluoro substitutions at the para and ortho positions of the phenyl ring introduce steric and electronic perturbations, altering metabolic stability. This compound arises as a synthetic byproduct during fluorination steps in Dolutegravir production. It serves as an HPLC reference standard for impurity profiling in API quality control.
