Chemical Structure
Description
4,4,5,5-Tetrachloro-2,2-difluoro-1,3-dioxolane (CAS 87075-01-2), molecular formula C3Cl4F2O2 and molecular weight 247.84 g/mol, is a CATO reference standard with documented purity and traceability.
4,4,5,5-Tetrachloro-2,2-difluoro-1,3-dioxolane (C3Cl4F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4,4,5,5-Tetrachloro-2,2-difluoro-1,3-dioxolane 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.
