Upon illumination with ultraviolet light exceeding 300 nm and in the presence of oxygen, it serves as an energy donor, facilitating the generation of singlet oxygen through triplet-triplet energy transfer. This process enables the highly reactive oxygen species to interact with 4-thiouracil, leading to the formation of uracil and uracil-6-sulfonate; the latter exhibits fluorescence around a wavelength of approximately 390 nm. Additionally, 4-Thiouracil functions as a substrate for T. gondii uracil phosphoribosyltransferase, allowing the synthesis of 4-thiouridine monophosphate for subsequent integration into RNA.\u003c\/p\u003e\n  \u003ch2\u003eSafety \u0026amp; Regulatory\u003c\/h2\u003e\n  \u003cdiv class=\"bhp-warning-box\"\u003e\n    \u003cp\u003e\u003cstrong\u003eFor Research Use Only (RUO).\u003c\/strong\u003e Not for therapeutic, diagnostic, or clinical use.
