New Arrivals

TimTec scientists closely monitor the direction of life-science research to ensure relevant chemical materials re-supply to match current trends in screening. New compound families are designed and synthesized on a regular basis.

Our compound collections offer greater diversity as we have balanced the combination of in-house synthesis and outside sourcing. Our researchers ensure a high diversity score from collection to collection. We prefer avoiding combinatorial chemistry approach in library design and all our molecules are hand-synthesized. Our compounds are stored in dry form and are freshly prepared in DMSO.  TimTec offers a variety of screening collections to suit different in capacity and design/purpose assays. Chemical compounds in our library collections are available for re-supply from our US stock.

Quality Control and Compound Purity

TimTec determines structure and purity of all compounds by using NMR and mass spectrometry. Our compounds have an average purity of 95%, and the minimum purity is at least 90%. We randomly check the quality of our stock compounds on a regular basis to confirm stability and shelf life. 1H-NMR spectra are available upon request for all stock compounds.
