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.

Didanosine CRS (Chemical Reference Standard) is used in system suitability testing to verify that analytical methods like HPLC or UV analysis are working correctly. A known concentration of Didanosine is analyzed to check parameters such as retention time, peak area, resolution, tailing factor, and theoretical plates, ensuring the system is accurate, precise, and reliable before testing actual samples.
