Application

Tegafur has been used as an internal standard for the analysis of 5′DFCR (5′deoxyfluorocytidine) and 5′DFUR (5′deoxyfluorouridine) using HPLC techniques. Tegafur has also been used as an internal standard for the chromatographic assay of azidothymidine (AZT).

Biochem/physiol Actions

Tegafur is a pro-drug of 5-fluorouracil, an antimetabolite used as an antineoplastic agent. It has been used as adjuvant chemotherapy for curatively resected colorectal cancer therapy.

Preparation Note

Tegafur is soluble in DMSO at a concentration that is greater than 50 mg/ml.
