Analysis Note
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
Application
Leflunomide may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using chromatography techniques.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
General description
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Leflunomide belongs to the new class of immunomodulating drugs with inflammatory and immunomodulating properties. It has been investigated for application in transplantation procedures. It is also an anti-rheumatic drug (DMARD) used to treat rheumatoid arthritis (RA). Its mode of action involves the inhibition of T-cell proliferation after converting to its active metabolite i.e. A771726 in humans.
Other Notes
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Leflunomide is an oral disease-modifying antirheumatic drug administered to patients with rheumatoid and psoriatic arthritis. This drug inhibits dihydroorotate dehydrogenase, an enzyme critical in the production of intracellular pyrimidines, and down-regulates tumor necrosis factor-alfa activity. Leflunomide has demonstrated usefulness in
