Chemical Structure
Description
As a certified reference material (CRM), Linezolid Impurity 117 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.
Linezolid Impurity 117 (CAS 352665-38-4) is a certified pharmaceutical impurity reference standard with the molecular formula C16H20N2O5 and a molecular weight of 320.34 g/mol.
Structurally, Linezolid Impurity 117 (C16H20N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 320.34 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
