Chemical Structure

Potassium perfluorononanoate CAS 21049-38-7 chemical structure

Description

Potassium perfluorononanoate (CAS 21049-38-7) is a high-purity analytical reference standard with the molecular formula C9HF17O2K and a molecular weight of 503.17 g/mol.

Potassium perfluorononanoate (C9HF17O2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.
