Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3-Difluoro-1-Methylcyclopropanecarbonyl Chloride (CAS 315690-85-8), molecular formula C5H5ClF2O and molecular weight 154.54 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Difluoro-1-Methylcyclopropanecarbonyl Chloride (C5H5ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 2,3-Difluoro-1-Methylcyclopropanecarbonyl Chloride 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.
