Chemical Structure
Description
Lenalidomide-d5 (CAS 1227162-34-6) is a high-purity analytical reference standard with the molecular formula C13H8D5N3O3 and a molecular weight of 264.29 g/mol.
Based on its molecular formula C13H8D5N3O3, Lenalidomide-d5 contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Lenalidomide-d5 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.
