Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 337.35 g/mol gives Linezolid R-Isomer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Linezolid R-Isomer (CAS 872992-20-6) is a high-purity analytical reference standard with the molecular formula C16H20FN3O4 and a molecular weight of 337.35 g/mol.
Based on its molecular formula C16H20FN3O4, Linezolid R-Isomer contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Linezolid R-Isomer 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.
