Acedoben is a pharmaceutical compound used to treat chronic hepatitis B. Acedoben stable isotopes are a series of isotopically labeled forms of the compound which are used in research and development. These isotopes are useful for tracking the distribution and metabolism of acedoben in biological systems, and for evaluating the safety and efficacy of new drug formulations. Acedoben stable isotopes are produced using advanced techniques such as isotopic enrichment and chromatography, and are highly pure and stable.
