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.

Celiprolol can be used in system suitability testing (SST) for HPLC or other chromatographic methods as a Certified Reference Standard (CRS). It helps verify that the system produces consistent retention times, sharp and symmetric peaks, proper resolution, and reproducible peak areas, ensuring accurate and reliable analysis of Celiprolol in pharmaceutical formulations.
