Chemical Structure
Description
The occurrence of 4,5,5,5-Tetrafluoro-4-(heptafluoropropoxy)pentanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,5,5,5-Tetrafluoro-4-(heptafluoropropoxy)pentanoic acid (CAS 243128-40-7) is a high-purity analytical reference standard with the molecular formula C8H5F11O3 and a molecular weight of 358.11 g/mol.
The molecular framework of 4,5,5,5-Tetrafluoro-4-(heptafluoropropoxy)pentanoic acid (C8H5F11O3) is characterized by 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.
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.
