1. Diazo compounds

We began with the manufacture and sale of synthetic dyes, further developing that technology for the manufacture of photosensitive materials and printing materials. Focusing on diazo compound synthesis, we later gained expertise in nitration reactions, amine reactions, oxidation-reduction reactions and halogenation reactions.

Reduction
reactions

Catalytic hydrogenation reactions using metal catalysts; reduction reactions and hydrazine reduction reactions using metal hydride compounds, sulfur compounds, etc.

Oxidation
reactions

Oxidation reactions using hydrogen peroxide, peracetic acid, chlorite, etc.

Halogenation

Synthesis of acid chlorides using thionyl chloride; halogenation using NBS, bromine, phosphorous oxychloride, etc.

2. Heterocyclic compounds

Our technology for making photography materials was developed based on our dye manufacturing technology. We are highly experienced in the synthesis of diazo and various heterocyclic compounds.

3. Other synthesis reactions

We make compounds for use as pharmaceutical intermediates, including pyrazole derivatives, quinoline compounds, thiazole derivatives, indazole derivatives, and indole derivatives. We have the equipment to perform multipurpose reactions such as Friedel-Crafts reactions, acylation and sulfonation, as well as cryogenic reactions at –90°C. We are capable of commercial-scale precision synthesis, such as using n-butyllithium and performing Grignard reactions, Suzuki-Miyaura cross-coupling reactions, and chiral pool synthesis. We have an excellent reputation among customers for production methods using multi-step reactions in a single pot. All our pharmaceutical intermediate manufacturing systems are GMP-compliant.
