An unknown impurity can raise important questions during pharmaceutical development. Where did it come from? What is its structure? And how can its identity be confirmed?

At Resonance Research Lab, we work through these questions step by step. Depending on the project, our scientists investigate unknown impurities, develop and perform impurity synthesis, purify the target compound, and establish its identity using complementary analytical techniques such as HPLC, GC, MS, NMR, and IR.

Our goal is not simply to produce analytical results, but to bring the different pieces of evidence together and provide a clear, scientifically supported understanding of the impurity.

Identify it, synthesize it, characterize it, and confirm it.
