Chemical Structure

Nitrosonium hexafluoroantimonate CAS 16941-06-3 chemical structure

Description

The occurrence of Nitrosonium hexafluoroantimonate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Nitrosonium hexafluoroantimonate (CAS 16941-06-3) is a high-purity analytical reference standard with the molecular formula F6NOSb and a molecular weight of 265.76 g/mol.

Based on its molecular formula F6NOSb, Nitrosonium hexafluoroantimonate contains fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 265.76 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.

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.
