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.

Oxytocin CRS (Chromatographic Reference Standard) is used in HPLC to provide a verified retention time that helps accurately identify the oxytocin peak in a sample. By comparing the sample’s chromatographic profile with the CRS, analysts can confirm the identity and purity of oxytocin with reliability.
