We provide custom manufacturing and process researching services for pharmaceutical ingredients and their intermediates from pre-clinical to commercial production stages. In addition, we offer analytical method development, stability testing, impurity identification, metabolite synthesis, and filing of drug master files (DMFs). Our company has various technologies for asymmetric synthesis, such as epoxidation, dynamic kinetic resolution, aldol reaction, and Michael reaction, for manufacturing optically active substances. We are involved in commercial production of prostaglandin derivatives through an original two-component coupling process. We specialize in multi-step synthesis, making best use of our experience in the manufacture of prostaglandins. We also specialize in production of heterocyclic compounds, making best use of our experience in the manufacture of original pharmaceuticals and agricultural chemicals.
