Leflunomide

Leflunomide Impurities & Reference Standards

Leflunomide is recognized as an active pharmaceutical ingredient (API) that supports formulation development, process validation, and quality assurance in drug manufacturing. Analytical laboratories rely on Leflunomide and its associated impurity standards for method development, quality control testing, and pharmacopoeial compliance (ICH, USP, BP, EP). Each batch of Leflunomide reference standard is accompanied by a Certificate of Analysis (CoA), HPLC purity data, and spectroscopic (NMR/MS/IR) characterization for use in pharmaceutical laboratories worldwide.
