Uracil is a pyrimidine base and a fundamental component of RNA where it binds to adenine via hydrogen bonds. It is converted into the nucleoside uridine through the addition of a ribose moiety, then to the nucleotide uridine monophosphate by the addition of a phosphate group.

Certified pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Uracil is one of the nucleotide bases of RNA. It is the precursor of DNA′s thymine. It acts like a carrier of genetic data and is hooked up with a ribose and three phosphates to form a ribonucleoside triphosphate once a human body produces nucleotides.
Safety Profile
Moderately toxic by
intraperitoneal route. An experimental
teratogen. Experimental reproductive
effects. Questionable carcinogen with
experimental tumorigenic data. Mutation
data reported. When heated to
decomposition it emits toxic fumes of NOx.
Purification Methods
Uracil crystallises from water (m 339-341o) and m 338o after sublimation in high vacuum. Its solubility in H2O at 20o is 1g/300mL. [Beilstein 24 H 312, 24 I 312, 24 II 169, 24 III/IV 1193.]
