Applications Oleuropein is a tyrosol ester derivative of elenolic acid and phenolic glycoside found in olive oil. Oleuropein shows antioxidant, anti-ischemic and hypolipidemic activity. Oleuropein has also been used as an immunomodulator . References Speroni, E. et al.: Phytother. Res., 12, S98 (1998); Andreadou, I. et al.: J.

Empagliflozin is a drug product that is used in the treatment of type 2 diabetes. It is an investigational drug and its development is still ongoing. Empagliflozin has been shown to have high purity and analytical standards, as well as metabolite standards. It also has a natural form, which makes it a niche product for research and development purposes. The impurity standard for this product is CAS No. 1620758-33-9 and it can be synthesized with high purity, providing the synthetic form of this drug product.

Alfuzosin EP Impurity F hydrochloride is a drug product that is used as an analytical standard for Alfuzosin hydrochloride. It is a natural, synthetic, and impurity standard that exhibits similar chromatographic properties to the API. The CAS number of this impurity is 19216-68-3. This product has a niche market because it is used in metabolism studies. It also exhibits high purity and pharmacopoeia grade quality.

2'-Deoxy-2',2'-difluorocytidine 5'-monophosphate (CDFMP) is a potent antitumor agent that has been shown to have a strong anti-angiogenic effect. It inhibits the cancer cell's production of microvessels and interferes with the formation of new blood vessels from pre-existing ones, which can be used to deliver chemotherapy drugs to the tumor. CDFMP is synthesized by reacting 2'-deoxy-2',2'-difluorocytidine with phosphoric acid and then converting it into the monophosphate form using phosphorus oxychloride. This drug is also resistant to platinum-based chemotherapy agents, making it a promising drug for patients who are resistant to other treatments.

Applications Verteporfin is a photosensitizer that is used in photodynamic therapy (PDT). Verteporfin can accumulate in tumor tissues allowing for 30 to 150 minutes optimal PDT after intravenous administration. References Levy, J.G.: Semin. Oncol., 21, 4 (1994)

Applications An isotopically labelled analog of Flurbiprofen (F598700). Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Chalmers, et al.: Ann. Rheum. Dis., 31, 319 (1972), Nishizawa, et al.: Thromb. Res., 3, 577 (1973)

Atracurium cis-Quaternary Ester Benzensulfonate is an impurity standard used in the manufacture of atracurium. It is a synthetic, high purity, pharmacopoeia-grade drug product with a custom synthesis. Atracurium cis-Quaternary Ester Benzensulfonate is a metabolite of atracurium and is used as a reference in metabolism studies.

Stability Hygroscopic Applications A labelled metabolite of Fluoxetine (F597100), a selective serotonin reuptake inhibitor which is used as an antidepressant. References Wong, D., et al.: J.
