Description
As a certified reference material (CRM), Lenalidomide-PEG5-C2-acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Lenalidomide-PEG5-C2-acid (CAS 2376139-68-1) is a high-purity analytical reference standard with the molecular formula C26H37N3O10 and a molecular weight of 551.59 g/mol.
Lenalidomide-PEG5-C2-acid (C26H37N3O10) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
