context_page_description: Alloxan, sometimes referred to as alloxan hydrate, is the name of the organic compound with the formula OC(N(H)CO)₂C(OH)₂. It is classified as a derivative of pyrimidine. The anhydrous derivative OC(N(H)CO)₂CO is also known, as well as a dimeric derivative. These are some of the earliest known organic compounds. They exhibit a variety of biological activities.
context_section_description: It was originally obtained by oxidation of uric acid by nitric acid. It is prepared by oxidation of barbituric acid by chromium trioxide.
  A dimeric derivative alloxantin can be prepared by partial reduction of alloxan with hydrogen sulfide.
