With a possibility to choose from almost 200 distinct classes, our updated collection of compounds now covers almost entire chemical space of 5-, 6- and 7-membered heterocycles, while not limiting itself to it. The presence of well-placed functions - acids, aldehydes, amines, hydrazines, isonitriles - in these highly diverse monomers makes them a perfect choice for early stages of drug discovery programs. The number of intermediates already available on a multi-gram scale has reached 2200 and is growing rapidly. The structures listed here can be synthesized in a matter of weeks and have a minimum purity of 95%.
