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.

Atracurium CRS (Chemical Reference Substance) used for peak identification is a certified standard that helps identify the correct peak of atracurium in chromatographic analysis (such as HPLC). By comparing the retention time of the sample with that of the CRS, analysts can confirm the presence and identity of atracurium. It ensures the method is specific and reliable, distinguishing atracurium from impurities or related substances.
