Chiral Building Blocks

One of our focuses is on developing technology for producing optically active compounds using asymmetric hydrogenation catalysts.
We manufacture many optically active compounds by combining our own patented technologies with technologies licensed to us by the Japan Science and Technology Agency (JST).
