Description
Fluorouracil Product Overview
Fluorouracil (C4H3FN2O2) is a white crystalline powder that is sparingly soluble in water. It is an analogue of uracil with a fluorine atom that blocks thymidylate synthase, an enzyme needed for DNA synthesis.
Pharmaceutical companies use it in solutions for intravenous injection in oncology, often in combination regimens, and in topical creams for certain skin conditions. It is also the active metabolite formed from Flucytosine inside fungal cells. Another antimetabolite API in our range is Gemcitabine Hydrochloride.
As a cytotoxic API, it requires contained handling and procedures for hazardous drugs. Zyntex supplies it only to licensed pharmaceutical companies with appropriate capabilities.
