About Tegafur

Vaqora Chemicals supplies Tegafur, a high-purity reference standard of Tegafur registered under CAS number 17902-23-7. Its molecular formula is C8H9FN2O3 and its molecular weight is 200.17 g/mol. Its systematic (IUPAC) name is 5-fluoro-1-(oxolan-2-yl)pyrimidine-2,4-dione. Common synonyms include Sinoflurol and Fental.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

As a reference sample of Tegafur, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Tegafur in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
