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.

Dihydrotachysterol for system suitability CRS (Chemical Reference Substance) is a certified reference material used in pharmacopeial testing to verify that analytical systems, such as HPLC, are functioning properly before sample analysis. It helps confirm parameters like resolution, peak symmetry, retention time, and reproducibility, ensuring the accuracy and reliability of dihydrotachysterol assay and impurity testing according to official standards.
