(S)-Naproxen Ethyl-d5 Ester

(S)-Naproxen Ethyl-d5 Ester is a deuterated form of the nonsteroidal anti-inflammatory drug (NSAID) Naproxen. It is commonly used as a reference standard in pharmacological and toxicological studies due to its unique chemical properties. Naproxen is an effective painkiller and anti-inflammatory drug used to treat a variety of conditions like arthritis, menstrual cramps, and migraine headaches. (S)-Naproxen Ethyl-d5 Ester is a deuterated analog of the drug that contains five hydrogen atoms replaced with deuterium atoms. This chemical modification does not affect the pharmacological properties of Naproxen but makes it useful for pharmacokinetic studies. The deuterated form of the drug is particularly useful in tracing the metabolism, absorption, and excretion of the parent drug and its metabolites in the body. It is also used in the development of new drug formulations with improved pharmacokinetic properties. Chemically, (S)-Naproxen Ethyl-d5 Ester has a molecular weight of 287.38 g/mol and a melting point of 65-68°C. It is a white crystalline powder that is soluble in organic solvents like methanol, ethanol, and chloroform. The drug is stable under normal storage conditions, but it should be kept away from heat, light, and moisture to prevent degradation. In conclusion, (S)-Naproxen Ethyl-d5 Ester is a valuable tool for drug development and pharmacological research. Its unique chemical properties make it an essential reference standard in the pharmaceutical industry.
