4-Acetamido D3-antipyrine

4-Acetamido D3-antipyrine is a chemical compound that is primarily used in pharmaceutical research and development. It is a deuterated analog of antipyrine, which is a non-steroidal anti-inflammatory drug that is used to relieve pain and reduce fever. The deuterated form, 4-Acetamido D3-antipyrine, has an additional three deuterium atoms, which make it useful in pharmacokinetic studies. Pharmacokinetics is the study of how drugs are absorbed, distributed, metabolized, and excreted in the body. Deuterium labeling is a powerful tool in this field as it provides a way to track the fate of a drug in the body. The deuterium atoms in 4-Acetamido D3-antipyrine act as stable isotopic labels that allow researchers to distinguish the drug from its metabolites in biological samples. The chemical formula of 4-Acetamido D3-antipyrine is C13H13D3N2O2, and its molecular weight is 246.33 g/mol. It is a white to off-white crystalline powder that is soluble in water and ethanol. It has a melting point of 155-157°C and a purity of at least 98%. Overall, 4-Acetamido D3-antipyrine is a valuable tool in pharmaceutical research as it allows for the accurate measurement of drug metabolism and pharmacokinetics. Its deuterium labeling provides a way to track the fate of a drug in the body, which is essential for drug development and safety evaluation.
