(aR,ßR)-ß-(2,4-Difluorophenyl)-ß-hydroxy-a-methyl-1H-1,2,4-triazole-1-butanoic Acid D3

(aR,ßR)-ß-(2,4-Difluorophenyl)-ß-hydroxy-a-methyl-1H-1,2,4-triazole-1-butanoic Acid D3, also known as Diflunisal D3, is a deuterated form of the nonsteroidal anti-inflammatory drug (NSAID) diflunisal. This compound is used in research studies as an internal standard for mass spectrometry and isotope dilution assays. Diflunisal D3 has a molecular formula of C14H8D3F2N2O3 and a molecular weight of 297.30 g/mol. It is a white to off-white crystalline powder that is sparingly soluble in water but soluble in organic solvents such as ethanol and methanol. Diflunisal D3 works by inhibiting the production of prostaglandins, which are responsible for inflammation and pain in the body. It is commonly used to treat conditions such as arthritis, gout, and chronic pain. However, like all NSAIDs, diflunisal D3 has potential side effects. These include gastrointestinal issues such as nausea, stomach pain, and ulcers, as well as an increased risk of heart attack and stroke. It is important to use this medication only as directed by a healthcare professional and to closely monitor for any adverse effects. In conclusion, diflunisal D3 is a deuterated form of the NSAID diflunisal used in research studies as an internal standard for mass spectrometry and isotope dilution assays. While it is effective in treating pain and inflammation, it is important to use this medication with caution and under the guidance of a healthcare professional.
