Voriconazole [CAS: 137234-62-9] is an antifungal medication commonly used prophylactically and treats fungal infections in lung and bone transplant patients.

Voriconazole: Use and Commercial Availability 

Voriconazole is an antifungal agent belonging to the triazole class, sharing structural similarities with fluconazole but exhibiting an expanded range of activity. It is frequently used as a preventive measure and for treating fungal infections in patients who have undergone lung and bone transplants. Additionally, it treats invasive fusariosis and scedosporiosis.

Voriconazole is available under the brand name Vfend.

Voriconazole Structure and Mechanism of ActionVoriconazole Structure and Mechanism of Action

The chemical name of Voriconazole is (αR, βS)-α-(2,4-Difluorophenyl)-5-fluoro-β-methyl-α-(1H-1,2,4-triazol-1-ylmethyl)-4-pyrimidineethanol. Its chemical formula is C16H14F3N5O, and its molecular weight is approximately 349.31 g/mol.

Voriconazole inhibits fungal cytochrome P-450-mediated 14 alpha-lanosterol demethylation. Its antifungal activity is due to the accumulation of 14-alpha methyl sterols.

Voriconazole Impurities and Synthesis

Voriconazole impurities can arise during synthesis1 due to the storage or use of specific raw materials and intermediates in manufacturing. These impurities encompass related compounds, degradation products, and process impurities. Stringent quality control measures and analytical methods are crucial to ensure the purity and safety of Voriconazole for patient use.

Daicel provides a comprehensive Certificate of Analysis (CoA) for Voriconazole impurity standards, such as Voriconazole Diastereomer (2S,3S/2R,3R) impurity, Voriconazole EP Impurity A, Voriconazole EP Impurity C, Voriconazole Impurity-15 and Voriconazole EP Impurity D. The CoA includes detailed characterization data such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additionally, upon delivery, we give a complete 13C-DEPT. Daicel possesses the technology and expertise to synthesize any unknown Voriconazole impurity or degradation product.
