We have strong self-development, advanced production, inspection equipment and instrumentation.With several years€™ research, we have fixed on chiral synthesis in raw pharmaceuticals and their intermediates. Our main research or products include Carbapenems such as Imipenem, Penipenem, Meropenem, Biapenem, Ertapenem, BO-2502 and CS-834, together with key intermediates for 1b-mehgylcarbapenem such as 4-caetoxyazetidin-2-one (4-AA or 4-ABA), b-methylazetidin-2-one (1-BMA or 4-BMA) and main intermediate1b-methyl vinyl phosphate (MAP or MVP) and several side-chains of corresponding Carbapenems.We have also produced Macrocyclic musk such as Muscone, Cyclopentadecanone, Pentadecanolide, Musk-T and Musk-105.
