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.

Flunarizine Chemical Reference Standard (CRS) is used in analytical laboratories to ensure system suitability during chromatographic methods like HPLC. It serves as a benchmark for retention time, peak shape, and resolution, confirming that the analytical system is working properly before testing actual samples. This ensures accurate, reliable, and reproducible results in quality control and routine analysis of flunarizine-containing formulations.
