Pharmaceutical Raw Materials

Since its establishment in 1922, we have provided a broad range of high purity laboratory chemicals and reagents. We manufacture pharmaceutical raw materials by utilizing reagent manufacturing technology, which we have acquired and improved over the last decades.

CertiPro Series Products

All CertiPro Series products are manufactured under the Good Manufacturing Practice (GMP) guidelines for Active Pharmaceutical Ingredients (API) to meet quality risk assessments and strict regulations of the industry. Furthermore, all CertiPro Series items are tested regarding bacterial endotoxins. Apart from that we provide supplementary information for residual solvents and elemental impurities (some services require additional charges).

Japanese Pharmacopoeia (JP) ・ Japanese Pharmaceutical Codex (JPC) ・ Japanese Pharmaceutical Excipients (JPE)

We carry a wide selection of pharmacopoeia-graded products. They are manufactured and packaged according to GMP guidelines.

CertiPro Series Products

  • All CertiPro Series products are endotoxin tested.
  • Additional tested for European Pharmacopoeia (Ph.Eur.) and United States Pharmacopeia (USP). The test content varies depending on the item.
  • Various reports like residual solvent or elemental impuries can be issued. (some services are chargeable)

Japanese Pharmacopoeia (JP)

JP was established and published to regulate the properties and quality of drugs by the Minister of Health, Labour and Welfare after hearing the opinion of the Pharmaceutical Affairs and Food Sanitation Council (PAFSC).
The JP consists of general notices, rules for crude drugs, preparations, tests as well as processes, apparatus and official monographs. Selected entries in the JP are highly important to health care regarding the necessity of the drug in medical practice, wide application and experience of use.

Japanese Pharmaceutical Codex (JPC)

JPC is a standard created for important ingredients which are not listed in the JP. It is determined by notifications from the Pharmaceutical Safety Bureau of the Ministry of Health, Labor and Welfare.
In 1982, the “Japanese standards of pharmaceutical ingredients,1982” was published and whose name was changed to “Japanese Pharmaceutical Codex” in 1993.

Japanese Pharmaceutical Excipients (JPE)

JPE is a standard for pharmaceutical additives not listed in the JP. The latest version was published in 2018.
