Several methods can be approached to modify the physico-chemical properties of the Active Pharmaceutical ingredients.
Here in this research work the designated supramolecular synthon approach, with a strategy to exploit acid-amide and acid-chloride
heterosynthons has been used to prepare Aceclofenac-Nicotinamide molecular complexes.
The molecular complexes were prepared by neat grinding (ACF-NI NG) and solution crystallization methods with DMSO as solvent (ACF-NI).
FTIR, DSC,
Mass analysis and SEM has been used to study the prepared molecular complexes. The results conclude the successful formation of the ACF-NI and ACF-NI NG molecular complexes.
Appearance of single DSC endothermic peak and in the FT-IR results,
changes observed in the vibrational frequencies associated with amide, acid and chloride groups of the reactants prove to be effective diagnostic features to confirm the formation of molecular complexes
