Juzen Chemical was established in 1950 as a manufacturer of antihistamines and pharmacopoeia drugs, and then, entered the organic intermediates field in 1956 with the production of monochloroacetic acid.

After that, Juzen Chemical expanded the business field to contract manufacturing services for value added intermediates and APIs.

Today, in the global pharmaceutical companies, outsourcing has become a prevailing trend, and the pace of this trend seems to be accelerating.

Against this background, Juzen Chemical is aiming to be the best partner and CDMO for global pharmaceutical companies, which can provide services as one-stop service, covering all stages from research and development support and manufacturing of investigational drugs to stable supply of commercial products. To achieve this, we are now actively working on acquisition of new technologies and investing in equipment.

In 2015, we built a state-of-the-art GMP compliant plant, capable of multiple-APIs production. Owing to the completion of this plant, which is equipped with a wide range of GMP compliant equipment, our quality assurance system was enhanced from the hardware aspect, in addition to the existing software quality assurance.

Furthermore, based on the organic synthesis industrialization technologies we long nurtured, integrated service that covers all stages from development of new drugs to the commercial production has become available by using the small-scale production plant that complies with the investigational drugs GMP along with other plants.

In addition to the cost advantage of the multi-item production system, we will be able to offer more attractive prices by using the existing multi-purpose intermediate plants in a collaborative way.

In 2017, responding to the demand of the times, we launched CMC solution service business, leveraging our experience and expertise. We have assisted pharmaceutical companies in many activities, including development of manufacturing routes and analytical method test method development.

In 2024, we carried out the expansion of the GMP-compliant API plant, as well as increasing equipment for nucleic acid medicines, as we are taking on new modalities.

In the rapidly evolving global pharmaceutical industry, we, Juzen Chemical, are confident in our capability of meeting the diverse needs of our customers with our world-class technological expertise.
