Our present collection of Stock Structures (US and Abroad) exceeds 100,000 readily available synthetic organic compounds. Additions to our Stock are made on a regular basis. All compounds are available on a cherry-pick basis in vials and/or microtiter plates in the amounts designated by our purchasers. New Arrivals
There are new compounds that are arriving at TimTec on a regular basis. If you would like to be among the first to be able to select from these groups, please contact us about our Preferred Customer Privileges. 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. The following compound collections are available: General Screening

Drug-like Characteristics of Compounds All of our compounds possess drug-like characteristics. LogP, Molecular weight, number of H-bond donors and acceptors as set forth in the Lipinski "Rule of Five" can help to determine strong candidates for drug-like characteristics. Lipinski rule of five requirements -
H-bond donors < 5 -
H-bond acceptors < 10 -
Log P < 5 -
Mol. Weight < 500 
1 - compounds which satisfy 1 requirement - 1% of all compounds
2 - compounds which satisfy 2 requirements 2% of all compounds
3 - compounds which satisfy 3 requirements 6% of all compounds
4 - compounds which satisfy all 4 requirements 91% of all compounds
