Beschreibung

Leflunomide Working Standard (Secondary Reference Standard), CAS 75706-12-6, is a precisely characterized impurity reference material with an assigned purity value and comprehensive analytical documentation. Supplied as a stable crystalline solid, the impurity is defined by its molecular mass and melting point, with chromatographic retention behavior specified for reversed phase HPLC. The certificate of analysis details identity confirmation by LC-MS and NMR, purity and related substance profile by validated HPLC, water content by Karl Fischer, and measurement uncertainty. Lot traceability to the primary reference, documented stability data and recommended storage conditions ensure consistent performance for impurity profiling and method verification.
