Finasteride EP Impurity A is a critical reference standard used in pharmaceutical quality control to monitor synthesis byproducts of the 5-alpha-reductase inhibitor. Its molecular formula is C19H28N2O2 with CAS No. 164607-08-9. This impurity typically arises during the condensation steps of the finasteride manufacturing process.
Strictly handle as a controlled substance; avoid skin contact due to potential hormonal activity. Store in a cool, dry place under inert atmosphere away from light to prevent degradation.
