As a manufacturer of inorganic sulfur compounds, we have combined our technologies related to for sodium sulfide and sodium hydrosulfide with the precision organic synthesis technologies we have accumulated in the course of our wide-ranging contract manufacturing and original product development efforts. Thus, we are engaged in the research, development and manufacturing of organic sulfur compounds. In addition to thiolation and sulfidation using our own inorganic sulfur compounds as raw materials, we also possess advanced synthesis technology using hydrogen sulfide and sulfur chloride, both of which are difficult to work with. When handling these sulfur compounds, there is an unavoidable odor problem, and we of course have high-performance deodorizing equipment in place, taking care to minimize the impact on the local environment.
