Megestrol Acetate EP Impurity J
Megestrol Acetate EP Impurity J is a defined impurity of megestrol acetate, the synthetic progestin used in hormonal therapy and as an appetite stimulant in cachexia. Its formula C24H34O4 and molecular weight of 386.52 place it among the steroidal degradation and process-related impurities that require monitoring in the drug substance and its oral formulations. A characterised standard of this kind supports method development and validation, particularly for stability-indicating separations, as well as identification and confirmation of impurity peaks, system suitability assessment and the preparation of calibration standards for quantitative impurity determination. The material is a white to off-white solid, stored at -20 °C (±5 °C) and shipped with ice packs. Pack sizes offered are 10 mg, 20 mg, 25 mg, 50 mg, 55 mg, 60 mg, 100 mg and 200 mg.
