Chemical Structure
Description
As a certified reference material (CRM), 2,2,3,3-Tetrafluoropropanoic anhydride 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.
2,2,3,3-Tetrafluoropropanoic anhydride (CAS 337-83-7), molecular formula C6H2F8O3 and molecular weight 274.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2,3,3-Tetrafluoropropanoic anhydride (C6H2F8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 274.07 g/mol, it falls into the medium-molecular-weight range. 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.
