Chemical Structure
Description
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.
Tetraethyl (1-fluorobut-3-ene-1,1-diyl)bis(phosphonate) (CAS 1312032-28-2), molecular formula C12H25FO6P2 and molecular weight 346.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetraethyl (1-fluorobut-3-ene-1,1-diyl)bis(phosphonate) (C12H25FO6P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
