    Betamethasone Impurity J EP

    Controlled Product
    CAS:
    <p>Betamethasone impurity J EP is a pharmacopoeia impurity standard. It is the most potent and stable of the betamethasone metabolites, and it is used as a reference standard for HPLC methods.<br>Betamethasone impurity J EP was synthesized using an improved method that does not include boron trifluoride etherate in the final stage of the synthesis. This impurity has been shown to have an analytical retention time of 4.5 minutes on HPLC, which corresponds to its molecular weight of 353.4 daltons.</p>
