Certificate of Analysis with potency report. Each Standard Material SER (Structure Elucidation Report) with NMR, Mass, IR spectral interpretation. This whole analytical document can be included in eCTD, ANDA, DMF submissions to regulatory agencies.

Estradiol valerate is used as a reference standard in system suitability tests for chromatographic methods, such as HPLC, to ensure the analytical system is functioning correctly. It helps evaluate parameters like retention time, peak shape, resolution, and reproducibility, confirming that the method meets Current Regulatory Standards (CRS) before analyzing actual samples. Its consistent and well-characterized chromatographic behavior makes it a reliable compound for validating system performance.
