Chemical Structure
Description
The occurrence of Perfluoro-4-methoxybutanoic acid (PFMOBA) 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.
CATO supplies Perfluoro-4-methoxybutanoic acid (PFMOBA) (CAS 863090-89-5), a certified reference material (molecular formula C5HF9O3, MW 280.05 g/mol) for analytical method development and quality control.
The molecular framework of Perfluoro-4-methoxybutanoic acid (PFMOBA) (C5HF9O3) 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.
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.
As a certified reference material (CRM), Perfluoro-4-methoxybutanoic acid (PFMOBA) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
