Xanthine
Xanthine (CAS: 69-89-6, C5H4N4O2) is a purine derivative, a heterocyclic organic compound essential in the biochemical processes of most living organisms. It serves as a precursor in the biosynthesis of uric acid and is a component of nucleic acids. Xanthine is also employed as a key intermediate in chemical synthesis, particularly for the production of various pharmaceutical compounds and research chemicals. Tech Serve Solutions provides Xanthine with a high purity assay.
