| Background: | During the synthesis of baricitinib, several unknown impurities have been identified, such as lactone impurity, dimer impurity, and hydroxymethyl impurity. These impurities have been isolated, and their structures have been confirmed through extensive analysis of NMR and mass spectrometry. Baricitinib Impurity 73（1 - (1 - ethoxyethyl) - 5 - (4,4,5,5 - tetramethyl - 1,3,2 - dioxaborolan - 2 - yl) - 1H - pyrazole）is often used as an intermediate in the synthesis of various pharmaceuticals and biologically active molecules. Its unique structure, containing a pyrazole ring and a boronate ester group, endows it with specific reactivity and properties. |
