Chemical Structure
Description
CATO supplies 2-Butenedioic acid, 1-(2,2,3,3-tetrafluoropropyl) ester, sodium salt , polymer with ethenylbenzene and sodium 2-butenedioate (CAS 72845-29-5), a certified reference material (molecular formula C7H6F4O4C4H2O4C8H8Na, MW 471.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H6F4O4C4H2O4C8H8Na, 2-Butenedioic acid, 1-(2,2,3,3-tetrafluoropropyl) ester, sodium salt , polymer with ethenylbenzene and sodium 2-butenedioate contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 471.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
