Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Perfluoro(2-ethoxyethane)sulfonic Acid.
Perfluoro(2-ethoxyethane)sulfonic Acid (CAS 113507-82-7) is a high-purity analytical reference standard with the molecular formula C4HF9O4S and a molecular weight of 316.10 g/mol.
Perfluoro(2-ethoxyethane)sulfonic Acid (C4HF9O4S) contains a carbohydrate-derived structure, a sulfone group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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(2-ethoxyethane)sulfonic Acid 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.
