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.

Fenoterol System Suitability CRS is used in analytical testing, particularly in HPLC or other chromatographic methods, to verify that the analytical system is performing correctly before sample analysis. It helps assess parameters such as peak resolution, retention time, and peak shape, ensuring accurate, precise, and reliable measurement of fenoterol in bulk drugs or formulations, and supporting method validation and regulatory compliance.
