Chemical Structure

Perfluorooctane Sulfonic Acid Potassium Salt CAS 2795-39-3 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 Perfluorooctane Sulfonic Acid Potassium Salt.

Perfluorooctane Sulfonic Acid Potassium Salt (CAS 2795-39-3) is a high-purity analytical reference standard with the molecular formula C8F17O3SK and a molecular weight of 538.21 g/mol.

Based on its molecular formula C8F17O3SK, Perfluorooctane Sulfonic Acid Potassium Salt contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 538.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
