  • Structure of the impurity.
  • Name of the Parent drug.
  • Required quantity.
  • CAS number of impurity (if available).

Isolation and Purification service is also provided as per clients’ request. All pharmaceutical impurity standards and related compounds are provided with certificate of analysis (CoA) along with the complete characterization data like 1H-NMR, IR, MASS, HPLC Purity etc. On request, we also provide additional data like 13C-NMR, CHN, TGA, Water Content, Volatile Content, Potency, Assay etc.
