Chemical Structure
Description
As a certified reference material (CRM), dimethyl 2-(3,3-difluoropropyl)propanedioate 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.
dimethyl 2-(3,3-difluoropropyl)propanedioate (CAS 1781090-76-3) is a high-purity analytical reference standard with the molecular formula C8H12F2O4 and a molecular weight of 210.18 g/mol.
Based on its molecular formula C8H12F2O4, dimethyl 2-(3,3-difluoropropyl)propanedioate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 210.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
