Allopurinol 13C4

Allopurinol 13C4 is a stable isotope-labeled version of Allopurinol, a medication used to treat gout and kidney stones. Allopurinol works by reducing the amount of uric acid in the body, which can build up and form crystals in the joints and kidneys, causing pain and inflammation. Allopurinol 13C4 is chemically identical to the non-labeled version, but it contains four carbon atoms that are replaced with the stable isotope carbon-13. The chemical formula for Allopurinol 13C4 is C5H2N4O, and its molecular weight is 141.09 g/mol. It is a white to off-white crystalline powder that is slightly soluble in water and has a melting point of 350-360°C. Allopurinol 13C4 is typically administered orally in tablet form, with dosages ranging from 100-800 mg per day depending on the severity of the condition being treated. It is metabolized in the liver and excreted in the urine. The half-life of Allopurinol 13C4 is approximately 1-2 hours, and it is eliminated from the body within 24 hours. While Allopurinol 13C4 is generally well-tolerated, it can cause side effects such as rash, fever, liver damage, and low blood counts. It may also interact with other medications, so it is important to consult a healthcare provider before taking Allopurinol 13C4 or any other medication.
