MonomerChem Inc has saved pharmaceutical and biotechnology centers tens of thousands of budgeted dollars by providing low cost scaled arrays of compounds with rapid turnaround times. These focused libraries provide scores of analogues and SAR information at low cost due to the efficient methods we employ in their production. The chemistry steps may include reductive aminations as well as hydrogenations, heating and low temperature. We have provided an image of a sample focussed library which could be completed in 4 - 6 weeks with compounds rolling out with in 2 weeks.
