Technical Data:

We will provide complete documentation support for every Standard Material. All analytical reports such as ¹H NMR, ¹³C NMR, Mass, FT-IR, HPLC Purity/GC Purity/QNMR Purity, Water content by KF/ Loss on Drying/TGA (Thermo-gravimetric Analysis). 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.

Lynestrenol is used in CRS studies to identify peak plasma concentrations, helping determine the timing of maximum progestogenic activity. This aids in optimizing dosing schedules and ensuring effective contraceptive coverage.
