Chemical Structure
Description
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.
2,2-Difluoroethyl methyl carbonate (CAS 916678-13-2) is a high-purity analytical reference standard with the molecular formula C4H6F2O3 and a molecular weight of 140.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2,2-Difluoroethyl methyl carbonate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2,2-Difluoroethyl methyl carbonate 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.
