Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 307.26 g/mol gives Lenalidomide Impurity 38 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lenalidomide Impurity 38 (CAS 874760-71-1) is a certified pharmaceutical impurity reference standard with the molecular formula C13H13N3O6 and a molecular weight of 307.26 g/mol.
The molecular framework of Lenalidomide Impurity 38 (C13H13N3O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
