ethyl 2-(2,3-dihydro-[1,4]dioxino[2,3-c]pyridin-7-yl)-2,2-difluoro-acetate (CAS 2230727-39-4) is a high-purity analytical reference standard with the molecular formula C11H17F2NO4 and a molecular weight of 265.25 g/mol.
The molecular framework of ethyl 2-(2,3-dihydro-[1,4]dioxino[2,3-c]pyridin-7-yl)-2,2-difluoro-acetate (C11H17F2NO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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), ethyl 2-(2,3-dihydro-[1,4]dioxino[2,3-c]pyridin-7-yl)-2,2-difluoro-acetate 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.
