Dienogest CRS (Chemical Reference Standard) is used in pharmaceutical analysis to ensure the accuracy, precision, and reliability of analytical methods like HPLC or UV spectroscopy. By analyzing a known concentration of Dienogest, system suitability parameters such as retention time, peak area, resolution, and tailing factor are checked before testing actual samples, ensuring consistent and valid results.
