Chemical Structure
Description
2,2-Difluoroethyl difluoroacetate (CAS 1300698-74-1), molecular formula C4H4F4O2 and molecular weight 160.07 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H4F4O2, 2,2-Difluoroethyl difluoroacetate 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 160.07 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2-Difluoroethyl difluoroacetate 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.
