Our Services

We offer sound knowledge-led expertise in synthetic organic chemistry coupled with strong analytical chemistry for meeting the challenging synthesis projects for your molecules.

Since its establishment, Hodogaya Chemical has been synthesizing diverse samples ranging from existing substances to unknown (new) compounds based on the synthesis technology accumulated through the exploratory research on agricultural chemicals, development of electronic materials such as CCA and OPC, and various experiments on phosgene reactions. They range widely from intermediates for pharmaceutical and agricultural chemicals to electronic materials and monomers.
We can respond to the request for contracts on a project basis or fixed term contracts (FTE). We can also propose synthetic routes and provide assistance in process development. We not only perform laboratory-scale synthesis to produce samples weighing several mg to several kg, but also conduct small-quantity trial production by utilizing our outsource network. If you are looking for an outsourcing contractor, we would be grateful if you could include us for your consideration.
