Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 286.27 g/mol gives Diethyl 2-fluoro-2-(((methylsulfonyl)oxy)methyl)malonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl 2-fluoro-2-(((methylsulfonyl)oxy)methyl)malonate (CAS 2710-86-3) is a high-purity analytical reference standard with the molecular formula C9H15FO7S and a molecular weight of 286.27 g/mol.
The molecular framework of Diethyl 2-fluoro-2-(((methylsulfonyl)oxy)methyl)malonate (C9H15FO7S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Diethyl 2-fluoro-2-(((methylsulfonyl)oxy)methyl)malonate 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.
