Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name URACIL.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Uracil

Uracil is a common and naturally occurring pyrimidine nucleobase in which the pyrimidine ring is substituted with two oxo groups at positions 2 and 4. Found in RNA, it base pairs with adenine and replaces thymine during DNA transcription. It has a role as a prodrug, an allergen, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a human metabolite and a Daphnia magna metabolite. It is a pyrimidine nucleobase and a pyrimidone. It is a tautomer of a (4S)-4-hydroxy-3,4-dihydropyrimidin-2(1H)-one. — ChEBI
