Pharmaceutical Characterization and Analytical Chemistry Services

ImQuest BioSciences has integrated medicinal chemistry, LC-MS analytical and bioanalytical chemistry and NMR services as a component of our PharmaSENS platform to enable the rapid development of a safe, effective, and successful pharmaceutical products. These services are available for small molecules, natural products, oligonucleotides and other biologic products. Our synergistic approach helps facilitate more rapid movement of a potential drug from hit to lead screening, to candidate identification, and IND-directed in vitro/in vivo studies. PharmaSENS allows the optimization of a pharmaceutical product identified in efficacy and toxicity screening and provides ongoing support for PK/PD studies. Contact us to learn more.
