ustom Synthesis

Our core business is in the small-scale (milligram to gram) synthesis of pharmaceutical active organic compounds for research purposes. If you can draw it, we can synthesize it.
Isotopically Labeled and Unlabeled Reference Standards

 

We specialize in small-scale synthesis of:

- APIs
- Metabolites
- Impurities
- Analogues
- Intermediates

With decades of combined experience, we are experts in the synthesis of stable labeled APIs and metabolites. Our extensive experience allows us to place deuteriums in the most stable positions to limit exchange, which ensures the quality of your assay. In cases where deuterium labeling is not desirable, we happily rely on 13C or 15N.

We are a registered DEA lab for Schedules II to V controlled compounds.

Quality Matters

Are you buying poorly characterized and unsupported reference standards? You don't need to settle for TLC or single wavelength purity determination.

With our full chemical certification, you will never need to doubt the authenticity or purity of Chemtos reference standards. Every compound provided by Chemtos comes fully certified with Diode Array HPLC purity analysis, proton NMR analysis, LC/MS and all of the supporting data. All analytical work is done under GLP conditions. See a sample Certificate of Analysis.
