Chemical Products

Developing unique products in the fields of pharmaceutical intermediates and electronic materials

The foundation of our Chemical Products business originated with the advances in industrial handling technology obtained during the production of sulfur dyes and dye intermediates made by our founder, Masakazu Utsunomiya.
Based on this sulfurization technology, we are currently able to provide unique products, such as pharmaceutical intermediates, electronic materials, resin additives, cosmetics, and aids to the surface treatment of copper plating.
Of particular note, we are the only manufacturer in Japan of “1-thioglycerol (thioglycerin)” and “3-mercaptopropan sulfonate sodium”, and we provide these to various companies.
In addition, with the focus today on global environmental issues, we are working proactively to create environmentally friendly products that make use of water-based technology.
