Chemical Structure
Description
The occurrence of Potassium 2,2-difluoro-3-methoxy-3-oxopropanoate is closely related to a carbohydrate-derived structure, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium 2,2-difluoro-3-methoxy-3-oxopropanoate (CAS 1803598-83-5), molecular formula C4H3F2O4K and molecular weight 192.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Potassium 2,2-difluoro-3-methoxy-3-oxopropanoate (C4H3F2O4K) contains a carbohydrate-derived structure, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 192.16 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
