7-Methyl-3-methyluric Acid D3

7-Methyl-3-methyluric Acid D3, also known as 3-Methyl-7-methylxanthine, is a derivative of caffeine that is used as a reference standard in analytical and clinical chemistry. This compound is a deuterated version of 7-Methyl-3-methyluric Acid, which means that it contains a non-radioactive isotope of hydrogen (D) instead of the usual hydrogen (H) atom. This deuterated version is used in various research applications as it helps in the accurate determination of the concentration of the non-deuterated compound in biological samples. 7-Methyl-3-methyluric Acid D3 is a purine derivative that has a molecular formula of C8H8N4O3D3. It is a white to off-white crystalline powder that is soluble in water and organic solvents such as methanol and ethanol. This compound is stable under normal conditions and has a melting point of 230-235°C. In terms of chemical properties, 7-Methyl-3-methyluric Acid D3 is an analogue of caffeine and theobromine. It is a weak inhibitor of phosphodiesterases, which are enzymes that break down cyclic nucleotides such as cAMP and cGMP. This compound has also been shown to have antioxidant properties and may help in reducing oxidative stress in the body. Overall, 7-Methyl-3-methyluric Acid D3 is a useful compound for researchers and scientists who are studying the metabolism and pharmacokinetics of caffeine and related compounds. Its deuterated form allows for accurate quantification of the non-deuterated compound in biological samples, which is essential in various analytical and clinical applications.
