Description
As a certified reference material (CRM), 4-[(3-fluoro-4-nitrophenyl)methyl]morpholine 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.
4-[(3-fluoro-4-nitrophenyl)methyl]morpholine (CAS 552883-91-7) is a high-purity analytical reference standard with the molecular formula C11H13FN2O3 and a molecular weight of 240.23 g/mol.
Based on its molecular formula C11H13FN2O3, 4-[(3-fluoro-4-nitrophenyl)methyl]morpholine contains a nitrogen-containing heterocyclic scaffold, 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 240.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 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.
