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.

Primidone for system suitability (CRS) is used as a reference standard to ensure the proper performance and reliability of chromatographic systems. It helps verify key parameters such as resolution, retention time, and peak reproducibility, ensuring accurate identification and quantification of primidone during analytical testing.
