A look at the implementation of the new United States Pharmacopeia (USP) chapters and the International Conference for Harmonization (ICH) guidelines for elemental impurities from an historical perspective, providing insight into the changes and considering the challenges and opportunities that lie ahead as the industry embraces the new methodology.

Carboxylates are made by reacting carboxylic acids with strong bases such as inorganic hydroxides. Carboxylates contain two unique carbon–oxygen “bond and half” linkages that coordinate with a metal ion to give two strong infrared peaks, which make them easy to see.

Fourier transform infrared (FT-IR) and attenuated total reflection (ATR)-FT-IR spectroscopic imaging are important tools for understanding molecular interactions. Sergei G. Kazarian of Imperial College London has used these advanced imaging techniques in a wide range of applications.
