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.

Furosemide is used as a peak identification Chemical Reference Standard (CRS) to confirm the correct retention time and identity of the drug in chromatographic analyses. It ensures reliable identification and consistency of analytical methods such as HPLC in pharmaceutical quality control.
