Chemical Structure
Description
The occurrence of 5-Fluorosulfonylperfluoro(2-methyl-3-oxapentanoyl) fluoride is closely related to a carbohydrate-derived structure, a sulfone group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Fluorosulfonylperfluoro(2-methyl-3-oxapentanoyl) fluoride (CAS 4089-57-0), a certified reference material (molecular formula C5F10O4S, MW 346.10 g/mol) for analytical method development and quality control.
The molecular framework of 5-Fluorosulfonylperfluoro(2-methyl-3-oxapentanoyl) fluoride (C5F10O4S) is characterized by a carbohydrate-derived structure, a sulfone group, 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.
CATO manufactures 5-Fluorosulfonylperfluoro(2-methyl-3-oxapentanoyl) fluoride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
